Three weeks after an Arlington man was stabbed to death, police now have some security video showing a man they call a person of interest in their investigation.
On July 6th, Roberto Lopez staggered into an Arlington convenience store with multiple stab wounds. He died at the hospital.
There's been little movement in the case nearly three weeks. But now, detectives are circulating security video from a nearby motel showing a man walking in the parking lot.
Witnesses reported seeing the man with Lopez the night of the stabbing.
