Ian MacDonald's Bond Set at $75,000 in Scottsdale Stabbing Death of Tyrice Thompson

Bond was set at $75,000 for the 26-year-old Tempe man arrested in the murder of former ASU football player Tyrice Thompson, and new information has been released in the case.

For starters, according to court documents obtained by New Times, although Ian MacDonald -- the man accused of stabbing Thompson to death outside the Martini Ranch bar in Scottsdale -- had blood on his shirt, it doesn't appear to be Thompson's blood.

A probable-cause statement submitted by police note that this is "preliminary" DNA testing, and more testing will be done on MacDonald's shirt.

Thompson was stabbed eight times -- the initial report was five times -- and died a few days after the January 27 attack, although he never regained consciousness after being stabbed, and was unable to tell police who did it.

It doesn't appear that anyone else witnessed the stabbing, but police have stacked up some details.

First of all, MacDonald was the first 9-1-1 caller.

"It should be noted that the Defendant was the [first] 911 caller who advised that his Girlfriend has been stabbed in the face by a Bouncer who took off running," the probable-cause statement says.

Obviously, police noticed that MacDonald's girlfriend, 22-year-old Samantha King, had not been stabbed in the face.

Police asked MacDonald about the blood on his shirt, as well as what appear to be fresh wounds on his hands and wrists.

MacDonald said that all happened when he fell inside Martini Ranch, although MacDonald and King gave conflicting answers about what happened with their scuffle with Thompson outside the place.

In interviews with police, both MacDonald and King denied that MacDonald had stabbed Thompson, and it appears that nobody else saw the actual stabbing. King admitted that she and MacDonald were in a physical fight with Thompson outside of Martini Ranch, but MacDonald denied that he had punched or stabbed Thompson at all, police say.

According to court documents, MacDonald said he always carried a knife with him -- except that night.

However, a probable-cause statement cites three anonymous acquaintances of MacDonald, who said MacDonald admitted to them he had the knife -- and stabbed Thompson.

One person said MacDonald had asked for help getting rid of the knife after the stabbing, and the other two told police that MacDonald admitted he'd chucked it in a dumpster in Mesa.

According to court documents, MacDonald's only lived in Arizona for six months. His Facebook page identifies him as a member of the Navy, although court documents state that he's an active-duty Marine.

He's been charged with second-degree murder.
