Investigators have jailed two teenagers in the deadly shooting of another teen whose body was dumped on a Metairie street Tuesday afternoon.
Meanwhile, the survivor of a deadly shootout Wednesday in River Ridge hasn't been arrested, but the investigation into the case is ongoing, authorities said Thursday.
In the Metairie case, Valentin Martinez and Chicobi Smith, both 17, were booked on second-degree murder counts in the slaying of Tyris James, also 17, Jefferson Parish Sheriff's Office spokesman Glen Boyd said.
James had a gunshot wound to his head when his body was discovered in the 2300 block of North Arnoult Road, between West Napoleon Avenue and Interstate 10.
Witnesses said his body had been pulled out of a car and left on the street before the vehicle drove off.
James lived one street over in the 2300 block of Edenborn Avenue. The Sheriff's Office said he was killed during an argument that erupted while he was in the car from which he was later dumped.
The agency has not yet discussed a motive for the slaying or how it identified Martinez, of Kenner, and Smith, of Metairie, as suspects.
Bail for each was set at $500,000 Thursday. They were captured Wednesday.
Anyone convicted of second-degree murder in Louisiana faces mandatory life imprisonment, though defendants who are 17 or younger may receive the possibility of parole.
In the other case, Patrick Lebranch, 34, was in his apartment in the 11100 block of Newton Street when he exchanged gunfire with 27-year-old Garland McDowell of Kenner, Boyd said.
Both were taken to a hospital, where McDowell was pronounced dead and Lebranch was treated for a bullet wound to the leg.
The Sheriff's Office said the two men were in an argument when the shooting occurred, but it has offered no details.
Boyd said Lebranch hasn't been arrested in the case but stopped short of saying he had been cleared of wrongdoing.
