Virginia police say 4 bodies found are victims of the "shopping cart killer" — and "other victims" are possible

Police in Virginia say the discovery of four bodies at two different locations in the state are the work of a serial killer who used a shopping cart to transport his victims' bodies after meeting them on dating sites. 

At a press conference Friday, Fairfax County Police Chief Kevin Davis dubbed the suspect, 35-year-old Anthony Robinson of Washington, D.C., the "shopping cart killer."  Investigators believe there are likely more victims, possibly beyond Virginia and up the East Coast, CBS affiliate WUSA-TV reported.

"After he inflicts trauma to his victims and kills them, he transports their bodies to their final resting place literally in a shopping cart—and there's video to that effect," Davis said.
