Three people were killed and two others wounded in a shooting at a business park in Harford County, Maryland, authorities said.
Officers were called to Advanced Granite Solutions at the Emmorton Business Park on the 2100 block of Emmorton Park Road just before 9 a.m. Wednesday, the Harford County Sheriff's Office said.
The two people injured in the Maryland shooting were in critical condition at Baltimore's Shock Trauma Center, Gahler said Wednesday afternoon.
A Harford County Sheriff official called it a "targeted" attack and said they were looking for a suspect who was driving a black 2000 Chevy Acadia with DE tags.
Officials said Prince, who has a criminal history, fled the scene in a black 2008 GMC Acadia with DE plates PC64273.
He is thought to have sped away from the scene in a 2000 black Acadia, with a DE licence plate.
A manhunt is now underway for Prince, who is considered armed and unsafe.
The sheriff said authorities checked an Elkton home after the shooting, but Prince was not there. The police chief wouldn't elaborate the past history the victim and Prince had, other than to say: "This individual knew the people he wanted to shoot", Tracy said.
"We were very nervous", Hunt said.
The office park includes a number of buildings housing various businesses.
Mike Sullivan, who works at a business in the next row of buildings from Advanced Granite Solutions, told CNN affiliate WBAL-TV that a client with a CB radio warned him to take cover, citing reports of a shooter.
A witness to the shooting reportedly told WJLA that Prince gathered his coworkers for a meeting then opened fire. "We're actually locked in right now with three of our clients".
The Harford County Sheriff's Office confirmed the facts and asked the media to avoid spreading tactical positions.
Federal agents from the Bureau of Alcohol, Tobacco, and Firearms, ATF, are also on the scene to assist local police.
