WATERTOWN, Mass. — Massachusetts Gov. Deval Patrick says mass transit service is resuming in Boston even though one Boston Marathon bombing suspect is still on the lam.

Authorities in Boston had suspended all mass transit and warned close to 1 million people in the entire city and some of its suburbs to stay indoors as the hunt for one suspect went on. The other suspect, his brother, died in a desperate getaway attempt.

The brothers are suspects in Monday’s marathon bombings, which killed three people and wounded more than 180 others. The men are also suspected of killing a Massachusetts Institute of Technology police officer in his vehicle late Thursday.

Patrick reminded people to “remain vigilant if you are out.”
