A 62-year-old man who opened fire inside a primary care doctor’s office in Evergreen on Thursday night before taking his own life was previously a patient at the facility, the Jefferson County Sheriff’s Office said Friday.

Investigators identified Lance Black, an Evergreen resident, as the person who fired a shotgun 19 times inside the CommonSpirit Primary Care office at 32214 Ellingwood Trail.

Deputies began responding to calls about gunshots in the medical office at 4:23 p.m. Thursday and arrived on scene at 4:28 p.m., where they found broken windows, the sheriff’s office said in a news release Friday afternoon.

Deputies entered the building and found Black, armed with a shotgun, the sheriff’s office said. They tried to de-escalate the situation, but Black fatally shot himself.

Investigators found that Black shot at doors, walls, computers and other equipment during the shooting. No one was injured and no other businesses were damaged, other than a single round that entered a vacant office.
