Birdine's attorney, William Campbell, said prosecutors didn't have enough evidence to win a conviction.
“The jury looked at the evidence and did what they had to do and found him not guilty,” Campbell said.

In January 2002, prosecutors dismissed first-degree murder charges against Birdine in the July 1999 robbery and slaying of two people, court records show.
The charges were dropped after a judge ruled a convicted co-defendant in the case didn't have to testify in Birdine's trial.
