A detective says a man killed by a West Virginia woman who said he attacked her after they met through an online site had encounters with police in as many as 20 other states.

West Virginia authorities are trying to spread information to see if the 45-year-old Oregon man can be linked to unsolved deaths and disappearances in other areas. Detective Steve Cooper says the encounters included being stopped, investigated or interviewed

But authorities say so far, no history of major crime has surfaced involving Neal Falls.

Cooper says police found items including axes, knives, handcuffs and a shovel in his car. Police say the Charleston woman grabbed his handgun and fired it back over her shoulder as he choked her July 18.
