Findings:

Items 003419-04-02A and 003419-04-02D are positive mixtures as noted by 3 to 4 peaks at several loci.  By comparing the electropherogram of the victim (003419-S01), items 003419-04-02A and 003419-04-02D contain the DNA of the victim. 

Items 003419-04-02B, 003419-S03, and 003419-S05 can be conclusively matched to the victim (1 in 625,000,000 probability the samples do not belong to the victim). 

Items 003419-04-02C, 003419-S02, 003419-S04, 003419-S06, 003419-S08 and 003419-S09 represent an unknown donor, who has contributed to items 003419-04-02A and 003419-04-02D. (1 in 750,000,000 probability that the unknown donor does not contribute to said items).

Item 003419-S07 represents a third donor inconsistent with the victim or previous unknown donor. 

All unknown donors are male (Amelogenin locus containing 2 peaks).

So, we have Philips identified as positive on the scene.
And two unknown males.

Given that info,

I'd like to know the story with Grant. Why did Bruno name him sole beneficiary in his will?
Is this even true?

Is it possible that Grant is Brunos kid?

If so, then his DNA wouldn't show as being a relative to Philip.


Iys still very possoble we can put Grant at the scene with another male attacker.

I think it's time the detectives bring in this Kyle fella for questioning. 3 different individuals have dropped his name. He needs checked for injuries, request DNA swab, and to check if he's got a record.

Grant has no Alibi.
Ashley told the interviewing officers twice, that he started touching stuff and rearranging the crime scene.
Maybe Ashley wasn't in on it but is covering for Grant with his arrival time being the same as hers. And he's altering the scene but she doesn't realize?

Is there a Kyle/Grant link?

I'm mainly suspecting Grant and Benito right now. One of the biggest reasons being from the blood analysis. There were 2 unknown males at the scene. Grant had a nosebleed and a cut on his arm, and on Philip's left cheek there was a blood droplet...

I'm mainly suspecting Grant and Benito right now. One of the biggest reasons being from the blood analysis. There were 2 unknown males at the scene. Grant had a nosebleed and a cut on his arm, and on Philip's left cheek there was a blood droplet that was identified as AB-, matching Gran't blood type. Maybe Grant and Benito had teamed up on this? Maybe Grant had tried to distract/hold his father while Benito got ready to stab Philip from behind, and that's why his father punched him? the autopsy details also mentioned blue fingernail beds and blue undereyes.. could that have been grant suffocating his father because stabbing him didn't work as they had planned? and that's how the blood droplet got on his cheek? Multiple knifes had the victim's blood, and it shows that the killers had difficulties while killing Philip. One of the knifes also had AB- blood on the handle, and a different blood type's blood droplet on the kitchen floor, could that have been Philip injuring the person who stabbed him, and Grant getting another knife to help the killer out?
