A second teenager has been arrested in a deadly shooting last month during a suspected armed robbery on La Annie Drive.

Police announced Wednesday morning that Cortez Watson, 18, will be booked into East Baton Rouge Parish Prison on counts of first-degree murder, armed robbery and illegal use of a weapon. 

The Aug. 6 shooting left Alonge McClain, 19, dead from multiple gunshot wounds.

Watson's arrest came a few weeks after Lazarius Johnson, 18, was also arrested in the case. He faces the same counts, plus carjacking. Johnson was also injured in gunfire during the incident, then hospitalized for treatment and booked into jail upon his release from the hospital. 

Police have provided few details about the circumstances of the shooting and their investigation, including how detectives linked the two suspects to the crime.
