Teen arrested in Louisiana shooting got ride from scene from grandmother | Louisiana

A 17-year-old accused of murder in the Louisiana mall shooting that killed high school senior Martha Odom and wounded five others was arrested after his grandmother helped police track him down. Markel Lee, who is facing charges including first-degree murder, attempted murder, and illegal use of weapons, surrendered himself to authorities on Friday. Police believe the shooting stemmed from social media beefs and possible gang activity, but are continuing their investigation. The governor has pledged a targeted warrant sweep for those linked to the incident.
