Authorities in Orange County, California, say they've caught a serial killer preying on homeless men.
Prosecutors say Iraq wr veteran Itzoatl Ocampo stalked homeless men in Orange County, California, then killed them.
He apparently had already picked out his next victims when police arrested him.
"This 23 year old young man was a viscous killer. That he had in his mind a desire to kill people.. and that he followed through with that," says Orange County District Attorney, Tony Rackauckas.
Authorities showed off the military knife they say the vet used to murder four homeless victims.
Rackauckas says with each murder Ocampo stabbed the men more times. The last man was stabbed 60 times.
The suspect's family says he came back from Iraq a changed man.
Police have Ocampo under a psychological hold in jail, so his father and mother have not been able to see him.
Refuglo Ocampo, who is homeless himself, says his son is not a serial killer.
"I feel the authorities criminalized him and make him look.. my son to look like he's a criminal," he says.
The district attorney says Blood Hounds then led police to Ocampo.
"The defendant.. when we was contacted by the police had blood on his hands.. blood on his face," says Rackaukas.
Investigators also found bloody clothes and a knife near Ocampo.
He faces four counts of murder, if convicted he could face the death penalty.
