Not even the DA seems to know if he had an accomplice. Seems clear he drove some vehicle to the mall, presumably his brother-in-law's dark Civic. At the time of the killings, he only owned a motorcycle, I believe.
That mall is in an urban area. Where did he store Gianni's vehicle for a month? Every cop in town was looking for it. He did not have a lot of time to get rid of the vehicle that night. Strange.
Also, it came out in court that CM got into a motorcycle accident either the day of the killings or xmas day. He did something like $6,600 worth of damage to his motorcycle, possibly seen here in a photo from myspace:

That is a lot of damage. Not sure if he was injured or hospitalized afterwards. Did that delay his disposal of Gianni's car? More unanswered questions.
