Services were held Thursday morning at St. Ambrose Church in Old Bridge for 18-year-old Cristina LoBrutto.
LoBrutto was to be laid to rest Thursday afternoon.
LoBrutto and 24-year-old Bryan Breen were shot and killed while they worked the overnight shift at the Pathmark in Old Bridge last Friday.
Authorities said 23-year-old Terence Tyler then killed himself. Tyler was discharged from the Marines in 2010 after suffering from depression.
More than 300 people attended Breen's funeral on Wednesday.
