"It's kind of scary up here against the woods," he said. "If he was going to run, he was going to run toward our house."

Moore said that he hoped the officer would recover quickly and that he appreciated an automated phone call from Howard County with information about the suspect. His doors were locked and his house lights were on Wednesday night, he said.

"It kind of gives you an uncertain feeling," Moore said. "Hopefully they'll catch him soon."

The last Howard County officer killed in the line of duty was struck by a car in 2007, and another Howard County officer was injured in a friendly-fire shooting incident in 2000.

A Baltimore County officer, Jason Schneider, was fatally shot in August while serving a warrant in Catonsville.

Tryphenia Ellis-Johnson, co-owner of Liberty Tax at 8851 Gorman Road, said she left work early and was not around when the shooting took place, but that it worried her.

"It makes me more aware that I need to be more careful," she said Wednesday night. "It could be near my office, almost anywhere."
