BALTIMORE (WJZ) — It took police nearly half an hour to respond to a drive-by shooting in a quiet Baltimore neighborhood.

Monique Griego reports neighbors are on edge in Woodberry.

The quiet neighborhood doesn’t see much police action and that’s why people who live there are scared because someone fired a gun there early Sunday morning.

A bullet pierced through the front door of Dave Gilmore’s Woodberry home.

“It was about five feet from my head and landed about eight feet from my wife when it finally came to rest,” he said.

It went through a wall, into the family room and eventually landed on the kitchen floor.

Gimore, a writer, and his wife, a student, say they don’t know why anyone would shoot up their home.

“It’s very clear that someone was looking for somebody else or that it was just a random act of insanity,” he said.

Gilmore and his wife hid in their basement and waited for police to arrive—but the wait was longer than they expected. Gilmore called 911 at 1 a.m. He called back at 1:21 a.m. The first officer arrived at 1:27. The delayed response has neighbors worried.

“That’s unbelievable. That’s not safe,” said Teresa Davis.

WJZ went to city police to ask what took so long.

“It’s incredibly alarming for an incident like this to take place but we have to balance it against other incidents where people may be in danger and may be undergoing personal injury or harm,” said Anthony Guglielmi, Baltimore City Police spokesperson.

The police department has launched an internal investigation to find out why there was a delay in response time.

Gilmore says he is happy with the department’s investigation into the delayed response. He hopes it will help someone in the future who may need police right away.
