Police tracked down on Thursday the final person of interest in connection with the shooting of a Pennsylvania State trooper earlier this week, NBC10 reports

Kaymer Lewis was believed to have been in the car during Tuesday's altercation that began with a police pursuit on the Schuylkill and Vine Street expressways and ended in a fiery crash with a school bus.

Police said Lewis was not considered a suspect in the shooting of Trooper Patrick Casey, who was shot in the shoulder, allegedly by 17-year-old Giovanni Cotto, after the crash.

Philadelphia Police reportedly tracked down Lewis in a store in North Philadelphia after receiving a tip. He was arrested on an outstanding probation warrant, NBC10 reports. 

Lewis was being questioned as a witness to the shooting. Police said he was cooperative.

Cotto was charged with shooting and injuring Casey. He was arraigned on charges Wednesday morning and his bail was set at $3 million.

Casey, 31, was released from Hahnemann University Hospital on Wednesday.
