Two Killed, Homeowner Arrested in Shooting in Severn


A Columbia man and a Huntingtown resident died after being shot by a homeowner in the 7600 block of Sandy Farm Road in Severn in early July. Duwayne Mason, of Columbia, and Timothy John Kerr, of Huntingtown, both died of wounds from a shotgun fired by homeowner John Matthew Garrison.

According to initial reports, Garrison claimed that he saw the two men approaching his house wearing masks and thought they were armed. He told police that he went in his house, got his gun and warned the two that he would shoot if they tried to enter. When Mason and Kerr attempted to kick down the front door, Garrison opened fire, striking both men. Kerr died in his vehicle while trying to leave the scene and Mason died in a home down the street, where he had gone to seek help.

In a search of Garrison’s home following the incident, police found nearly 200 grams of cocaine, a quantity of amphetamines, a digital scale and more than $6,000 in cash. Garrison was arrested on drug charges.
