It happened Thursday around 2:30pm at Columbia Machine, Inc., a concrete mold manufacturer in Smithsburg, Maryland.

The Washington County Sheriff’s Office says the 23-year-old worker there was on a regularly scheduled shift, when he went to get a gun from his vehicle and opened fire on multiple co-workers inside the company break room.

Three employees died including, 50-year-old Mark Alan Frey, 31-year-old Charles Edward Minnick Jr., and Joshua Robert Wallace, 30.

A fourth worker, 41-year-old Brandon Michael, was left injured.

The shooter then fled the scene in his Mitsubishi Eclipse but was quickly tracked down by a Maryland State trooper, leading to a shootout.

Both the trooper and the suspect were wounded. The trooper has since been released from the hospital.

A search warrant of the suspect’s West Virginia home led to the recovery of multiple additional firearms.
