1
00:00:00,120 --> 00:00:02,920
Speaker 1: At the end of week three, more experts took to

2
00:00:02,920 --> 00:00:05,280
Speaker 1: the stand and one of the stars of the day

3
00:00:05,480 --> 00:00:10,119
Speaker 1: was the dehydrator, a dehydrator that Aaron Patterson lied about

4
00:00:10,200 --> 00:00:14,960
Speaker 1: dumping at a local tip put simply. Crown Prosecutor Narnette

5
00:00:15,000 --> 00:00:18,880
Speaker 1: Rodgers asked whether the DNA fingerprint of a deathcat mushroom

6
00:00:19,040 --> 00:00:22,119
Speaker 1: had been found in debris taken from this dehydrator.

7
00:00:22,720 --> 00:00:25,479
Speaker 2: The results of the testing using the various tests that

8
00:00:25,520 --> 00:00:29,200
Speaker 2: were available to you, including the genome sequencing and the

9
00:00:29,240 --> 00:00:34,960
Speaker 2: barcode sequencing, indicate the presence of Amanita filoides DNA in

10
00:00:35,000 --> 00:00:36,560
Speaker 2: the item setout in this table.

11
00:00:36,840 --> 00:00:40,280
Speaker 3: That's correct in samples four and seven of the dehydrater.

12
00:00:40,760 --> 00:00:43,080
Speaker 1: It was a day of technical evidence, but we're here

13
00:00:43,120 --> 00:00:46,440
Speaker 1: to take you through it. I'm Brook Greenbert Craig, and

14
00:00:46,479 --> 00:00:52,440
Speaker 1: this is the Mushroom cook. Day thirteen of Aaron Patterson's

15
00:00:52,479 --> 00:00:55,240
Speaker 1: murder trial is done and I'm back with court reporter

16
00:00:55,360 --> 00:00:58,760
Speaker 1: Laura POSSELLA. Hi, Laura, Hey, Brook. It was a short day,

17
00:00:58,840 --> 00:00:59,560
Speaker 1: wasn't it.

18
00:00:59,560 --> 00:01:03,440
Speaker 3: It's sure. As we've mentioned before, court on Friday finishes

19
00:01:03,480 --> 00:01:06,280
Speaker 3: at one pm, so everyone gets to go home early.

20
00:01:06,360 --> 00:01:09,360
Speaker 1: So this will be a shorter episode. But rest assured.

21
00:01:09,560 --> 00:01:13,679
Speaker 1: We'll have a subscriber episode that will go live on Sunday,

22
00:01:13,760 --> 00:01:17,039
Speaker 1: so stay tuned for that one. Now let's move on

23
00:01:17,160 --> 00:01:20,520
Speaker 1: to what we heard today. At the top of the episode,

24
00:01:20,760 --> 00:01:25,840
Speaker 1: you heard an exchange between doctor David Lovelock from Agriculture

25
00:01:25,880 --> 00:01:30,360
Speaker 1: Victoria and Crown Prosecutor Nannette Rogers, and they were talking

26
00:01:30,440 --> 00:01:35,120
Speaker 1: about the dumped dehydrator their words but not their voices.

27
00:01:35,520 --> 00:01:38,520
Speaker 3: And just to remind our listeners, this is the dehydrator

28
00:01:38,640 --> 00:01:43,240
Speaker 3: that Erin has admitted to dumping on August two. This

29
00:01:43,280 --> 00:01:46,480
Speaker 3: is about four days after the lunch We heard from

30
00:01:46,560 --> 00:01:50,120
Speaker 3: witness Darren Canty a few days ago, who manages the tip.

31
00:01:51,080 --> 00:01:53,720
Speaker 3: He told the court that he received a call from

32
00:01:53,760 --> 00:01:58,400
Speaker 3: police around August four making some inquiries about this dehydrator.

33
00:01:59,040 --> 00:02:02,320
Speaker 3: One of mister Canty his employees searched the bin at

34
00:02:02,320 --> 00:02:05,440
Speaker 3: the tip found the dehydrata and then that was later

35
00:02:05,520 --> 00:02:09,520
Speaker 3: seized by police. After police took hold of the dehydrada,

36
00:02:09,960 --> 00:02:13,000
Speaker 3: they have taken samples from it and then these samples

37
00:02:13,000 --> 00:02:14,320
Speaker 3: have been sent off for testing.

38
00:02:14,919 --> 00:02:18,520
Speaker 1: Some of that testing was carried out by doctor Lovelocke

39
00:02:18,960 --> 00:02:21,520
Speaker 1: and Laura, can you explain to the listeners who he

40
00:02:21,720 --> 00:02:22,760
Speaker 1: is and what he does.

41
00:02:23,280 --> 00:02:26,600
Speaker 3: So, as you mentioned, Brooke, he's from Agriculture Victoria and

42
00:02:26,639 --> 00:02:31,239
Speaker 3: he's a diagnostician. He received the samples from the dehydrata

43
00:02:31,480 --> 00:02:35,120
Speaker 3: on August eleven and he ran a series of tests

44
00:02:35,160 --> 00:02:38,120
Speaker 3: with people from his team. The court heard today that

45
00:02:38,160 --> 00:02:41,840
Speaker 3: he examined seven test tubes which were each filled with

46
00:02:41,919 --> 00:02:46,160
Speaker 3: samples from the dehydrata. He was asked about the results

47
00:02:46,240 --> 00:02:48,840
Speaker 3: of these tests that were conducted and he said that

48
00:02:49,040 --> 00:02:52,560
Speaker 3: two of the seven test tubes came back positive for

49
00:02:52,600 --> 00:02:55,840
Speaker 3: Amanita filoides, which is of course death cap mushrooms.

50
00:02:56,480 --> 00:02:59,960
Speaker 1: The jury also heard that he examined other things related

51
00:02:59,960 --> 00:03:04,360
Speaker 1: to the mill, including leftover beef Wellington, a jug of

52
00:03:04,400 --> 00:03:05,760
Speaker 1: gravy and a fruit platter.

53
00:03:06,240 --> 00:03:09,600
Speaker 3: And this marked another chapter in the journey of the Leftovers.

54
00:03:10,360 --> 00:03:14,040
Speaker 3: To remind everyone, the leftovers have gone from Erin's binn

55
00:03:14,160 --> 00:03:18,160
Speaker 3: at her home, to lean Gatha Hospital, to Monash Medical Center,

56
00:03:19,000 --> 00:03:22,400
Speaker 3: to the Royal Botanic Garden's office, to the home of

57
00:03:22,440 --> 00:03:25,480
Speaker 3: my collegist Camille Trung and then at this point we

58
00:03:25,560 --> 00:03:28,720
Speaker 3: hear they've arrived at doctor Lovelock's lab, most likely at

59
00:03:28,760 --> 00:03:29,959
Speaker 3: Agriculture Victoria.

60
00:03:30,320 --> 00:03:33,560
Speaker 1: Yes, they've definitely made their way around the state, and I.

61
00:03:33,520 --> 00:03:36,600
Speaker 3: Failed to mention that at some point they've then gone

62
00:03:36,640 --> 00:03:39,440
Speaker 3: to the Victorian Institute of Forensic Medicine by the end

63
00:03:39,440 --> 00:03:42,400
Speaker 3: of August. So we'll wait to see if there's any

64
00:03:42,440 --> 00:03:45,560
Speaker 3: other stops these leftovers make along the way, but for

65
00:03:45,640 --> 00:03:48,200
Speaker 3: now the court are hearing that they are at doctor

66
00:03:48,240 --> 00:03:51,520
Speaker 3: Lovelock's lab. On August two, he told the court that

67
00:03:51,640 --> 00:03:55,760
Speaker 3: two samples of these leftovers were tested and neither came

68
00:03:55,800 --> 00:03:58,000
Speaker 3: back positive for death cap mushrooms.

69
00:03:58,440 --> 00:04:00,880
Speaker 1: But he did say that he found white but the

70
00:04:01,040 --> 00:04:02,600
Speaker 1: mushrooms and beef.

71
00:04:03,080 --> 00:04:05,960
Speaker 3: That's correct, but he didn't just test the leftovers and

72
00:04:06,040 --> 00:04:09,080
Speaker 3: the debris from the dehydrator, as you said earlier, Brooke,

73
00:04:09,240 --> 00:04:12,360
Speaker 3: a jug of gravy and a fruit platter also made

74
00:04:12,360 --> 00:04:15,360
Speaker 3: their way to his lab. He said that he didn't

75
00:04:15,400 --> 00:04:18,040
Speaker 3: need to run any tests on the fruit platter after

76
00:04:18,120 --> 00:04:22,600
Speaker 3: observing it himself, but the jug of gravy was examined

77
00:04:22,920 --> 00:04:25,640
Speaker 3: and no traces of deathcat mushrooms were found.

78
00:04:25,760 --> 00:04:29,360
Speaker 1: Laura, you said earlier. By August twenty nine, the leftovers

79
00:04:29,400 --> 00:04:33,520
Speaker 1: had made their way to the Victorian Institute of Forensic Medicine.

80
00:04:34,120 --> 00:04:37,279
Speaker 1: One of the forensic toxicologists who works there returned to

81
00:04:37,320 --> 00:04:38,520
Speaker 1: the witness box today.

82
00:04:39,200 --> 00:04:42,680
Speaker 3: That's right, it was Dmitri Girista Mulis. He was back

83
00:04:42,720 --> 00:04:46,960
Speaker 3: in court today for cross examination and he was asked

84
00:04:46,960 --> 00:04:51,039
Speaker 3: a series of questions by defense barrister Colin Mandy about

85
00:04:51,080 --> 00:04:54,560
Speaker 3: the test results that came back of all of the

86
00:04:54,640 --> 00:04:58,080
Speaker 3: samples taken from the lunch guests as well as Erin

87
00:04:58,200 --> 00:05:02,720
Speaker 3: and her children. Listeners may remember that yesterday doctor Girista

88
00:05:02,760 --> 00:05:06,520
Speaker 3: Mulis was asked a number of questions around the amatoxins

89
00:05:06,680 --> 00:05:11,520
Speaker 3: present in these samples. Specifically, these are death cap amatoxins

90
00:05:11,680 --> 00:05:15,200
Speaker 3: called alpha amaneitin and beta amaniton.

91
00:05:16,400 --> 00:05:19,360
Speaker 1: And what did he say about Don Patterson's samples?

92
00:05:20,080 --> 00:05:23,200
Speaker 3: He told the court again today that don samples came

93
00:05:23,279 --> 00:05:28,160
Speaker 3: back positive for both alpha amaneiton and beta amaniton.

94
00:05:28,520 --> 00:05:30,120
Speaker 1: And that was in his urine, wasn't it.

95
00:05:30,520 --> 00:05:32,040
Speaker 3: Yes, that's right, And.

96
00:05:31,960 --> 00:05:33,480
Speaker 1: What did he say about the others then?

97
00:05:34,000 --> 00:05:36,359
Speaker 3: So he made a point today of explaining to the

98
00:05:36,440 --> 00:05:41,200
Speaker 3: jury that amatoxins are less detectable in blood samples than

99
00:05:41,200 --> 00:05:44,920
Speaker 3: they are in urine samples. The court heard that there

100
00:05:45,000 --> 00:05:48,800
Speaker 3: was no urine sample from Gail Patterson, so the tests

101
00:05:48,880 --> 00:05:51,560
Speaker 3: had to be run against her blood and it was

102
00:05:51,600 --> 00:05:55,320
Speaker 3: for this reason, he explained. The results came back showing

103
00:05:55,360 --> 00:05:58,839
Speaker 3: no presence for either alpha aminiton or beta amaniton.

104
00:05:59,360 --> 00:06:02,919
Speaker 1: Mister Mandy suggested to him that a person's ability to

105
00:06:03,000 --> 00:06:07,359
Speaker 1: recover from the ingestion of poisonous mushrooms would depend on

106
00:06:07,560 --> 00:06:10,480
Speaker 1: several factors. What did he say about that.

107
00:06:11,040 --> 00:06:14,599
Speaker 3: Yes, Doctor Gurrista Mullis agreed with mister Mandy that a

108
00:06:14,680 --> 00:06:19,719
Speaker 3: person's general health, their age, their weight, and even their

109
00:06:19,760 --> 00:06:23,920
Speaker 3: toxic response could weigh into how they would recover from

110
00:06:24,040 --> 00:06:28,240
Speaker 3: the ingestion of poisonous mushrooms. He also agreed that the

111
00:06:28,279 --> 00:06:32,400
Speaker 3: amount of mushrooms consumed and even the concentration of the

112
00:06:32,440 --> 00:06:35,800
Speaker 3: toxins within the meal could play a role in their

113
00:06:35,839 --> 00:06:40,200
Speaker 3: potential recovery. After he gave these answers in cross examination,

114
00:06:40,880 --> 00:06:44,480
Speaker 3: Crown Prosecutor Sarah Lenthal had a question for him in

115
00:06:44,680 --> 00:06:48,320
Speaker 3: re examination. The first time she asked his question, mister

116
00:06:48,400 --> 00:06:52,560
Speaker 3: Mandy actually objected and the jury left the room. But

117
00:06:52,720 --> 00:06:55,400
Speaker 3: later in the course of proceedings, mister Mandy said he

118
00:06:55,400 --> 00:06:58,680
Speaker 3: would withdraw his objection and the question was asked to

119
00:06:58,720 --> 00:07:02,480
Speaker 3: doctor Gurrista Mullis. This is the exchange between miss Lenthal

120
00:07:02,680 --> 00:07:06,360
Speaker 3: and the witness. These are their words, it's not their voices.

121
00:07:06,880 --> 00:07:10,360
Speaker 4: If two adults with no serious pre existing health conditions

122
00:07:10,440 --> 00:07:13,640
Speaker 4: consume the same amount of the same meal, which contained

123
00:07:13,640 --> 00:07:16,880
Speaker 4: death cap mushrooms, than one person dies, what would you

124
00:07:16,960 --> 00:07:19,440
Speaker 4: expect the health outcomes to be for the person who

125
00:07:19,480 --> 00:07:20,760
Speaker 4: did not die.

126
00:07:21,000 --> 00:07:23,360
Speaker 5: Yes, there would be likely that there would be some

127
00:07:23,440 --> 00:07:27,640
Speaker 5: adverse outcomes for that person who survived, the severity of

128
00:07:27,680 --> 00:07:30,160
Speaker 5: which may vary depending on some of the factors that

129
00:07:30,200 --> 00:07:33,760
Speaker 5: I've previously spoken about today. But we have had examples

130
00:07:33,800 --> 00:07:37,520
Speaker 5: where two people have consumed the same meal, and more recently,

131
00:07:38,120 --> 00:07:40,920
Speaker 5: this happened last year here in Victoria, where one person

132
00:07:41,000 --> 00:07:44,040
Speaker 5: passed away and the other one was significantly ill for

133
00:07:44,080 --> 00:07:47,640
Speaker 5: a period of time and ended up in ICU. So

134
00:07:47,920 --> 00:07:51,200
Speaker 5: it is possible, but it's it will depend on how

135
00:07:51,280 --> 00:07:53,920
Speaker 5: much is eaten, the person's response to that amount of

136
00:07:53,920 --> 00:07:54,679
Speaker 5: toxin as well.

137
00:07:55,440 --> 00:07:58,680
Speaker 1: And that was the end of his evidence. Thanks so much,

138
00:07:58,760 --> 00:08:01,920
Speaker 1: Laura for pronouncing Dimitri's surname for me. It was a

139
00:08:01,920 --> 00:08:04,480
Speaker 1: bit of a hard one, eld. And that also brings

140
00:08:04,560 --> 00:08:06,200
Speaker 1: us to the end of today's show.

141
00:08:06,600 --> 00:08:07,520
