from www.radaronline.com – The ex-Marine accused of murdering Cathouse prostitute Brooke Phillips and five others has made an emotional phone call to his mother insisting that he’s innocent of the horrific crime that shocked America, RadarOnline.com can reveal.

David Allen Tyner, 28, who is currently being housed in Oklahoma County Jail after being charged with six counts of murder, claims he is ‘holding-up’ despite all the publicity surrounding the shocking house fire.

Tyner’s friend, and former cage fighting promoter Jason Nicholson, told RadarOnline.com: “David called his mom last night and she told me that he was holding-up fine despite of everything.

“He is maintaining that he’s not guilty of the crimes that he has been accused of and he knows that he has a lot of people rooting for him.”

RadarOnline.com uncovered the partial autopsy reports detailing two of the victims Millie Barrera and TV hooker Brooke Phillips who were both pregnant when they were killed.

Barrera’s cause of death is listed as ‘perforating gunshot wounds to back and head and Phillip’s as ‘perforating gun shot wound to the head.”

Despite the reports findings – in what the police believe is a drugs related crime – Nicholson is adamant that his friend never took illegal substances and that he never saw him with a gun.

He added: “He wasn’t into drugs and I would be interested to know if any of the victims had drugs in their systems.

“All the time I knew him I never saw him firing off guns and although he has been charged by the police people should not assume that he is automatically guilty of these crimes.”

Tyner voluntarily gave himself up to the police after another witness told detectives that he had seen him inside the house in Oklahoma City prior to the shootings and subsequent fire.

Tyner was a two time state champion wrestler and a state- runner-up at Locust Grove High School as a senior in 2000 – he also wrestled at the University Of Tennessee Chatanooga and later joined the Marine Corps and served in Iraq.

Tyner then became a cage fighter and completed a 6-1 record in mixed martial arts fighting bouts in Oklahoma and Kansas City in 2006 and 2007 and was due to take part in another fight next month.

Jason Nicholson previously told RadarOnline.com that he though his friend suffered from Post Traumatic Stress Disorder after serving in Iraq.
