Investigators are trying to piece together the events that led to two teenagers dying in Lawrenceville this (Monday) afternoon.
Gwinnett Police responded to a home on Riverlanding Circle around 4pm to find one young man dead inside a make-shift shed and another dead outside the shed from a self-inflicted gunshot wound, according to multiple Atlanta news outlets.
Police spokeswoman Ashley Wilson says four boys met in the shed when one produced a gun, killing the first teen.
They believe the shooter then took his own life.
Both victims are between the ages of 16 and 18 and police have not released their identities.
