Friends of Michael Harding are heartbroken saying that he was scared in the weeks before he was found shot to death.
"He was in fear for, you know his life as well, because his doors was chained up, they were propped up. So like you were trying to keep someone out," said Preston Cleary.
The same day murder suspect O'Donnell was arrested at Sacramento International Airport, Julie Harding, who was on leave from CHP, was arrested for criminal trespassing in Tennessee, and released the same day. Those in the area say she tried to take her husband's dog from his girlfriend's house. Two days later, Julie Harding was found dead with the cause of her death unknown, but no foul play is suspected in that case. It is unknown if she knew murder suspect O'Donnell.
"Mike was truly just a good hearted individual. I hope to just see this over with and Mike can finally rest in peace," said Cleary.
