00:00:00
But finally, according to Debbie, 8 months later, >> 8 months >> 8 months later, the results finally
00:00:10
start coming in. The blood on Royy's shirt >> is Roiy's blood. No trace of Amber's. And that DNA under
00:00:21
her nails, not Royy's and not Josh's. >> Okay. Now the type of testing they have,
00:00:29
they were working with YSTR [music] testing which looks at genetic markers on the Y chromosome
00:00:36
>> and those get passed down from father to son. So all males along a direct [music]
00:00:42
paternal line have the same marker. >> So good news in this case, they have a match. It's McKini DNA.
00:00:52
Bad news, investigators can't say which one. It could be Michael or it could be Enk or it could be any other male in
00:01:01
that familial line for that matter. >> Yeah, but there wasn't any other family in the house that night.
00:01:06
>> Very true. So, with investigators knowing that they were the only two men from that family in the house,
00:01:13
>> and knowing that MK is the one who wasn't there when police showed up, and that he's the one who had scratches on
00:01:20
his arms when they met with him 3 days after the murder, MK is the one who is finally charged with Amber's murder.
00:01:29
>> The one So, just him. >> Yeah. They charge MK with murder and what will eventually be eight counts of
00:01:36
evidence tampering. But Michael and Josh get hit with evidence tampering charges,
00:01:40
too. And they all plead not guilty.
