An argument over entry to a house party on Broadway Avenue in Lawrence, Massachusetts, ended with the death of 18-year-old Richard Bonilla of Lowell. The disturbance began after three women were denied access and moved outside, where violence broke out. In the early morning hours of November 4, 2012, 20-year-old Ismael Calixto fired a gun into a parking lot across the street; Bonilla tried to flee and was shot in the back of the head. Police found him around 1 a.m. in the area of 400 Broadway. He was taken to Beth Israel Deaconess Medical Center in Boston and died later that day.

The Massachusetts State Police and the Lawrence Police Department identified Ismael Calixto as the shooter. At the time of the shooting he was reportedly in the custody of the Department of Youth Services for earlier gun charges and was supposed to be at home under a curfew. A Salem Superior Court jury found Calixto guilty of second-degree murder in March 2015; he was sentenced to 15 years to life in prison.
