BATON ROUGE - State troopers in Baton Rouge captured a teen "person of interest" in a New Orleans carjacking and homicide after a car chase Tuesday.

The Jeep Liberty reported to have been taken in the carjacking was spotted around 4:30 p.m. on Interstate 10 in Ascension Parish. Troopers tried to stop the Jeep, but the driver sped away, causing four separate wrecks on Siegen Lane before crashing into a trooper's police unit.

Troopers said the driver got on I-10 toward Siegen, drove the wrong way on Airline Highway back to Siegen, then tried to get on eastbound I-10 toward New Orleans. 

The 16-year-old suspect was arrested on a slew of traffic charges and with illegal possession of a handgun by a juvenile. Police described him as a person of interest in a May 22 killing in Orleans Parish.

A passenger in the Jeep was taken to a hospital to be examined, police said.

Earlier, Baton Rouge Police chased a suspect in an unrelated pursuit.  It ended in a crash in Central.
