BALTIMORE (WPVI) -- A neighborhood in Baltimore, Maryland is on lock down this weekend as police search for the gunman who killed one of their own.
Investigators say Detective Sean Suiter was shot and killed while canvassing the neighborhood for information on a homicide case Wednesday night. He was an 18-year veteran with the force.
Now, investigators are combing through surveillance video from the area, looking for evidence.
They believe the suspect may be injured.
"We're asking anyone with friends, family, acquaintances that know of anyone with a new, unexplained injury and their either seeking treatment unconventionally for that injury or not getting treatment at all," said Police Commissioner Kevin Davis.
The reward for information leading to an arrest in the case is now up to $190,000.
