"This is a deep and tragic loss for the USS Abraham Lincoln family," Navy spokesman Brian O'Rourke said in an emailed statement. "Our thoughts and prayers are with Petty Officer Brown's family and loved ones." O'Rourke told NBC 7 that Petty Officer 3rd Class Brown, who was from South Carolina, joined the Navy in February 2018. After boot camp and school, he was assigned to the USS Abraham Lincoln aircraft carrier and was stationed at Naval Base Coronado. Brown was living in an apartment in the 4300 block of Echo Court apartment when he was killed. Police responded to 911 calls for help in less than four minutes, but the shooters managed to run away, police said.
