Mehrens said MacDonald was part of the Fleet Antiterrorism Security Team during his four tours of duty, and said he didn't even know what it was that MacDonald did overseas, but said he knows it "involves guarding radioactive materials."
The judge said that she took into account MacDonald's military service when deciding MacDonald's bond, which was set at $75,000. Police had requested bond be set at $1 million.
Additionally, Mehrens pointed out some possible weaknesses in the case against his client.
"They have no eyewitnesses, they have no confession, they have no murder weapon -- they have exactly nothing," he said.
Additionally, MacDonald -- who's accused of stabbing Thompson to death outside the Martini Ranch bar in Scottsdale -- had blood on his shirt, but a "preliminary" DNA test showed it's not Thompson's blood, according to court documents obtained by New Times.
And, although four of Martini Ranch's employees were outside at the time, none of them saw the actual stabbing, according to a probable-cause statement. Two of them, who had just escorted MacDonald and his girlfriend out of Martini Ranch, left them in the parking lot to deal with another "disturbance" out there. The other two saw MacDonald, his girlfriend, and Thompson apparently brawling outside, but by the time they got over to them, Thompson had already been stabbed.
Thompson was stabbed eight times, and died a few days after the January 27 attack. He never regained consciousness after being stabbed, and was unable to tell police who did it.
MacDonald and his girlfriend denied any involvement in the stabbing, but police found some other details.
