David Edward Maust (April 5, 1954 - January 20, 2006) was an American serial killer whose primary targets were young boys.
He has been suspected or charged for five murders, including one in Germany while he was in the United States Army; one in the early 1980s; and three in Hammond, Indiana, where he was caught after the remains of the three victims' bodies were found under concrete in a residential basement. He had been considered mentally unfit to stand trial on multiple occasions.
An official biography about his life and crimes, Blood Stained: When No One Comes Looking, written by Dory Maust was released January 6, 2009.
