It's the last thing you would want to come back to after a long day at work.
Baltimore County police said 29 cars were broken into in the 5700 block of Southwestern Boulevard in Halethorpe.
All of the cars had the passenger side window smashed.
One driver told ABC2 his GPS was taken, and another had credit cards stolen.
Bruce Gear has been commuting and parking his car on Southwestern Boulevard for 12 years without a problem.
"They obviously were out here for a long time breaking into cars and took their time to go through everything and steal so it's a shame that hard working people come back and find their cars broken into," Gear said.
Police got the first call at 5:10 Wednesday evening but are not sure exactly when the cars were broken into.
