A New Jersey supermarket employee shot and killed two co-workers before taking his own life in the early hours of Aug. 31.
The gunman, who has been identified as 23-year-old former Marine, Terence Tyler, went on a rampage inside the Pathmark grocery store in Old Bridge, N.J. around 4 a.m., The Wall Street Journal reported.
Middlesex County Prosecutor Bruce Kaplan told reporters that shortly after leaving work at 3:30 a.m., Tyler returned to the store with an AK-47, multiple ammunition magazines and a handgun and fired 16 shots before killing himself.
Tyler first began shooting outside the store at an employee who ran inside to warn more than a dozen co-workers who were still inside, Associated Press said.
The Diocese of Meutuchen, N.J. told EWTN News Aug. 31 that they did not yet have a statement on the shooting, but were working to get the names of victims and contact information for their families.
During his two years as a Marine, Tyler never served overseas. He was described by his sister as depressed since the death of his mother in 2010, according to the Wall Street Journal.
Those killed were 18-year-old Cristina LoBrutto and 24-year-old Bryan Breen, both of whom were graduates from area Old Bridge High School.
Kaplan said he does not believe the victims were specifically targeted.
LoBrutto, who was scheduled to begin classes at nearby Brookdale Community College next week, was described by friends as cheerful and having a good sense of humor, The Star-Ledger reported.
Breen was a 2006 graduate of Old Bridge.
The victims' high school organized a candlelight vigil on the evening of Aug. 31.
