A man suffered life-threatening injuries after he was shot Tuesday morning in an exchange of gunfire at a house in the Delridge neighborhood of West Seattle, according to Seattle police.

Just before 11:30 a.m., the man went to a house in the 6900 block of 24th Avenue Southwest, where he was involved in an altercation with another person, says an item posted on the Seattle Police Department’s online blotter. The two exchanged gunfire and the man fled, collapsing on the street; the other person also fled and a police search is underway, the post says.

Officers provided first-aid to the wounded man until Seattle Fire Department (SFD) medics arrived.

SFD medics transported the 28-year-old man in critical condition to Harborview Medical Center, public-information officer David Cuerpo said in an email.

As of Tuesday afternoon, the man remained in critical condition, said Harborview spokesperson Susan Gregg.

According to the Seattle police blotter post, the house where the shooting occurred is known to officers assigned to the department’s Southwest Precinct and SPD is working with several city departments and neighbors to address community concerns about the residence. The blotter post does not elaborate.

An online search of SFD emergency reports shows firefighters have responded to the residence seven times since January.
