PHILADELPHIA (WPVI) -- New details are emerging about the suspect in a deadly shooting inside Wilmington Hospital on Tuesday, as authorities say the accused gunman, a hospital employee, is now in custody.
Police identified the suspect as 23-year-old John Wallace-Bey of New Castle.

Investigators allege Wallace-Bey shot two 19-year-old co-workers inside the facility, killing one and critically wounding the other.
Authorities say Wallace-Bey was arrested several hours later in Philadelphia's Olney neighborhood.
He is currently being held in Philadelphia following his arrest and has been charged with murder.
Officials say they tracked Wallace-Bey using license plate reader technology, which led them from Wilmington Hospital to Philadelphia. He was ultimately taken into custody at the corner of North 9th Street and Lindley Avenue.
Authorities said the suspect was located after investigators followed a Toyota RAV4 believed to be connected to the case.

Doorbell camera footage showed police towing the vehicle shortly after it arrived at the scene.
Additional video captured Wallace-Bey walking in the area shortly before officers, along with the FBI, moved in to make the arrest.

Wallace-Bey appeared before a Philadelphia judge, who denied bail. He now awaits extradition back to Delaware.
ChristianaCare confirmed that Wallace-Bey and the two victims were all hospital employees. Officials have not released any information about a possible motive, but investigators believe the shooting was a targeted attack.

"Just speechless that it happened. And it's an unfortunate situation and you hate to hear. Lives were lost yesterday. So, it's an unfortunate situation that happened," Richardson said.

Residents in the Olney neighborhood also reacted to the arrest, expressing relief that the suspect had been apprehended.
"Us as a community, we have to do better. Keeping these things from out of our community," said Terrence Thomas.
"They got the guy. So, less crime should be on the street now," another resident said.
Authorities have not released further details as the investigation continues.
