Suspect in Emmorton Business Park shooting identified

Gahler told reporters the suspect is Radeed Labeeb Prince, a 37-year-old black male, and showed media the suspect's photograph.

The two patients being treated at Shock Trauma are both in critical condition, Shock Trauma said on Twitter.

Sheriff Jeffrey Gahler said all the victims are though to have worked at the same company, Advanced Granite Solutions, where the killings took place. State police said they consider him "armed and risky". The men told him someone was shooting and he asked if they had called 911. Investigators believe Prince drove away in a black 2000 Acadia, with DE license plate PC064273.

The owner of Advanced Granite Solutions said Prince had been an employee there for four months, The Associated Press reported. "Certainly, we consider him armed and risky", he said.

The identities of the victims were not released immediately.

A co-worker sought a peace order against Radee Prince in February, saying Prince had punched an employee in the face and returned and threatened employees.

He said one time, Prince came to see him, and cursed and yelled at him.

The suspect was allegedly fired from a job earlier this year for attacking another employee. He was also charged with being a felon in possession of a firearm in Cecil County, Md.
