The Harford County Sheriff's Office is investigating six break-ins. In all those cases, the doors were unlocked. They say, locking your doors is common sense and the best way to ward off a thief.
One resident, Erik Rand, told WMAR 2 News he doesn't take chances when it comes to his safety.
"Just make sure that if you see that if you anyone suspicious we try to keep an eye on that sort of thing."
Police caught suspects on tape near where Rand lives. They were casing cars, checking to see if they were open. Officials are investigating six break-ins. The thieves hit Glenrothes Drive twice
Doefiled Court, May Apple Court, and Greentree Circle two times.
"It is very surprising to hear that it is going on in a neighborhood like this. We moved here because we thought it was a safe area," said James Horwath.
"Every night I make sure that the doors are all locked and I lock all the cars, make sure they're all locked up, check the windows," Horwath said.
The suspects entered all of the vehicles because they were left unlocked, something that's so easy to do. A break-in can happen anywhere at any time.
Harford County officials are investigating but are urging everyone to lock doors and windows every time you leave
