The suspect in the September shooting deaths of a suburban Chicago family was in a relationship with one of the four people slain and his girlfriend allegedly helped plan the killings, police investigators said.
Alberto Rolon, Zoraida Bartolomei, and their two sons, ages 7 and 9, were found shot to death on Sept. 17 in their home in Romeoville, about 30 miles (48 kilometers) southwest of Chicago. Days later, suspect Nathaniel Huey Jr., 31, died in a car crash in Oklahoma that also killed his girlfriend, Ermalinda Palomo.
