Jacobi Medical Center shooting suspect arrested after signing in

BRONX, New York City (WABC) -- The 25-year-old gunman who police say opened fire inside Jacobi Medical Center in the Bronx was arrested after he apparently wrote his name in the sign-in book when he arrived at the hospital.

Authorities say Keber Martinez spotted his 35-year-old victim inside the waiting area outside the hospital's emergency room Tuesday afternoon.

The two, who are believed to know each other, then got into a verbal dispute.

Martinez fired four shots, striking the other man once in the arm and sending everyone in the waiting area scrambling for safety.

John Jay Tashjian was driving on the New Jersey Turnpike when he noticed a car that crashed and landed in tall grass just outside of Newark.


Mayor Eric Adams said the shooting was possibly gang related and that the suspect "noticed a rival gang member, possibly."

"He pulled out a gun and shot the person," Adams said. "And sitting in the emergency room at the time were families, a child, and hospital staff."

The victim was rushed into the emergency room, while the gunman fled the scene.

In surveillance video obtained by Eyewitness News, the gunman is seen opening fire.
