Edwin Lohr is determined to claim victory over the violence in his North Park community. And he's doing it one stop at a time.
Lohr helped start the North Park Citizens Patrol a year ago.
Now as he walks down University Avenue, he says the organization is stepping up its presence since five women have been attacked in the area in less than two months.
"They better think twice because we’re going to get them," warned Lohr.
The latest assault happened Sunday morning near the corner of Lincoln Avenue and Kansas Street.
Police say a woman walking alone was clobbered in the back of the head and knocked out.
After she awakened, she walked home, officials said.
Investigators are trying to determine if it's tied to the other four assaults. Some have been sexual in nature.
Police have released a composite sketch of the man they say attacked two of the women - one on Lincoln, the other on Meade.
They’ve also released surveillance video of a person of interest in an attack on 33rd that happened in early June.
Citizens Patrol is arming residents with the ammo they need to protect their community.
They’ve passed out whistles and they’re putting flyers on doors alerting people to security problems.
