Editor's note: Authorities on March 1 confirmed a PennLive report that Deputy U.S. Marshal Christopher Hill was killed by friendly fire Jan. 18 while serving an arrest warrant with a task force of law enforcement officers. Police say Kevin Sturgis opened fire on police as they were arresting his girlfriend inside the Harrisburg home but he did not fire the fatal shot that killed Hill.

UPDATE: Deputy Marhshal killed by friendly fire when bullet came through wall

A deputy U.S. marshal fatally shot in Harrisburg in January was killed by friendly fire, multiple sources confirmed Thursday.

Christopher Hill was shot during an exchange of gunfire while serving an arrest warrant inside 1837 Mulberry Street on Jan.18 with a task force of deputy U.S. marshals and local officers.

Police originally said Kevin Sturgis opened fire on officers as they were arresting his girlfriend inside the house. That's still true, but sources confirmed to PennLive that Hill was not struck by one of Sturgis' bullets.

Instead, the bullet came from another officer's gun who was returning fire against Sturgis.

Sturgis' wife, Jenea Sturgis of Philadelphia said she was eager to see the truth come out about the fatal shooting. Police notified Sturgis' family Wednesday.

"I'm upset about it," she told PennLive. "The whole world thinks he's a murderer and he's the one that killed that officer. Our kids have to see that."

While the news of the ballistics results changes some things about the fatal shooting, law enforcement officials confirmed that Sturgis still fired the first shot and that his bullets struck two other officers who were wounded.

Police previously had never indicated that the shooting may have been the result of friendly fire, but PennLive noted two days after the shooting, after a tour of the house, that several bullet holes pierced the back of the stairwell where Sturgis had been standing.

The bullets that pierced that wall ended up in the dining room.

The team of nine officers was there to arrest Shayla Towles Pierce for a gun possession crime and two misdemeanors. Questions were raised from the beginning about whether Pierce was the true purpose behind the high-risk arrest warrant, as Sturgis also was wanted out of Philadelphia.

District Attorney Fran Chardo and Harrisburg Police Chief Thomas Carter declined to comment. U.S. Attorney Dave Freed also declined comment.
