GAITHERSBURG, Md. — A 37-year-old woman was arrested Sunday after allegedly drowning her 3-month-old daughter in a bathtub, according to Montgomery County police.
Mackenzie Rose Colgan, of Gaithersburg, contacted authorities at approximately 12:12 p.m., reporting that she had drowned her child while bathing her, police said in a statement.
Officers and fire rescue personnel responded to the 7300 block of Summit Avenue, where the infant was rushed to a nearby hospital. Despite life-saving efforts, the baby was pronounced dead.
