DC gym shooting kills 1, injures 4; gunman dead, sources say

A gunman is dead after shooting himself while barricaded by police in Logan Square apartment building Thursday morning in Washington, D.C. sources told Fox News. 

The standoff between the gunman and police occurred after he shot somebody inside a gym at Logan Circle in Washington, D.C, and injured at least four others during the rampage, according to D.C. Metro Police and sources. 

During the barricade, while communicating with the suspect, police heard a gunshot in the apartment he  was locked inside, D.C. MPD's interim chief of police Jeffery W. Carroll said during a Thursday morning press conference. 

After the gunshot, police broke down the door to find the suspect sustaining a self-inflicted gunshot wound, Carroll said. 

Two law enforcement officers briefed on the situation told Fox News that they were told the suspect is now dead. 

The suspect, a white male, also fired at officers from within the apartment building, Carroll added.

Of the four living victims who sustained injuries, one is in critical condition, according to Carroll. 

The shooting was reported around 8 a.m. near 15th and P streets, according to police.

Carroll revealed that MPD received calls after somebody was shot inside of Vita Fitness, a local fitness chain with a location in Logan Circle. 

"I was at the treadmill at Vida, and five minutes in, I hear a loud bang…and this dude was on the floor, and somebody says, who was closer to the body, ’he’s dead,’" witness Anthony Mirones said.

"I heard a loud bang, and then I see blood on the floor, I’m connecting the dots. Two minutes later, there’s a fire alarm, people started evacuating." Mirones added. 

Once outside, Mirones said gunshots were heard and "people started scattering everywhere."

Vida Fitness told Fox News the location will be shut down until further notice. 

"We are writing to inform you that VIDA Logan Circle is temporarily closed following a shooting that occurred earlier today," Vida's prsdient Aaron Moore wrote in an alert to members.

"We ask that you avoid traveling to the Logan Circle location and surrounding area until further notice. If you are currently in the vicinity, please follow all instructions from local law enforcement," the message added.

"The facility will remain closed until further notice. We will provide updates as more information becomes available and it is safe and appropriate to do so. Thank you for your understanding and cooperation during this difficult time," Moore's message concluded.

Carroll also told reporters that, while police are still working to ascertain the shooter's motives, they had documented a conflict he had with the homeowner's association of the apartment building in which he barricaded himself.

D.C. Mayor Muriel Bowser, who joined Carroll at the press conference, also weighed in. 

"We're devastated. Someone was killed in our city this morning in a senseless act of gun violence," Bowser told reporters. 

"I know many D.C. residents were awakened to this news, and were very scared, and listened to all of the directives that MPD provided, so we're grateful to them as well. MPD will continue to investigate this situation but this lone gunman has been contained," Bowser added.

The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) also responded to the shooting and is on scene assisting authorities, the Bureau's D.C. branch announced in a post on X.
