Photo of Dorothy Grubbs, missing from the North Point area.The boyfriend of a North Point woman reported missing Saturday was arrested on Merritt Boulevard this morning on an open warrant for a weapons violation. The woman, Dorothy Iris Grubb, 60, of the 1700 block of Manor Road, 21222, remains missing.

Clyde Campbell, 53, also of the Manor Road address, is in police custody and has not yet appeared before a court commissioner on the weapons violation, which is unrelated to the missing persons case. Police want to talk to Campbell to see if he has information that may help them find Dorothy Grubb.

Campbell's 14-year-old son was with him at the time of the arrest.

Campbell was driving a white Ford F-150 pickup truck when he was arrested.

Grubb's adult daughter called police Saturday at 6:30 p.m. to report that she had not seen her mother since Thursday evening and was concerned for her welfare because of a history of domestic violence with Campbell. The daughter said she had not seen Campbell, either.

Police began a missing persons investigation and on Sunday publicized the case, asking for the public's help in locating Grubb. Police have searched the Manor Road home, looking for information that might help them find Dorothy Grubb. The investigation is active and ongoing. Police consider Grubb a "critical" missing person because of concerns about her safety.

Grubb is a white female, 5'5" tall, 120 pounds, with brown hair and brown eyes. She was last seen wearing blue jeans and a T-shirt of unknown color. She has no known medical problems.

Anyone with information about this case should call Baltimore County Police at 410-307-2020.
