New details on last Friday's shooting on 34th Street just south of 39th Avenue.

Officials say forensic tests have revealed why the lieutenant fired several times.

They also say this is not the first time the 18-year-old Nicholas Weeks had a run-in with law enforcement.

According to officials, Weeks has a juvenile history that includes battery of a law enforcement official as well as mental health problems.

Lt. Hansen had to fire multiple gun shots at Weeks because Weeks kept coming and investigators confirmed by the location of the spent shells.

“There were multiple shots fired. Weeks was struck multiple times but what forensically we are starting to see is the shots did not stop him. He kept advancing on Lt. Hansen and that would explain the multiple shots,” said Lt. Keith Kameg.

Police are hoping more witnesses come forward.

Lt. Kameg says they know what happened from the time of the shooting but details regarding what brought Weeks to the middle of 34th Street are still unclear.
