Prosecutors say they suspect Chargers linebacker Steve Foley was on steroids when he was shot three times by an off-duty police officer. "His history of aggressive and even violent contact with law enforcement indicates the possibility of more than mere alcohol involvement," wrote criminal investigator Dan Nordell in an affidavit for a search warrant. "(Steroids) can cause erratic behavior in those that use them. This has been given names like 'roid rage for the uncontrollable outbursts and violence experienced by some users."
