Jason Mendez plundered Melissa and Sean Deloatch and their six children after a fierce dispute between Mendez and Sean Deloatch, according to a statement by the Haverstraw Police Department.
Then he drove back and drove back into the family, police said.
"The vehicle crashed into the building with such force and severely damaged the front of the building," reads the police brief. "The driver reset the vehicle and drove forward a second time when he met Deloatch and his family."
All family members were wounded and taken to hospital. Melissa Deloatch, the 32-year-old mother, eventually died from her injuries. The father, Sean Deloatch, and three of the couple's children were later transferred to another hospital, where they were treated for serious but not life-threatening injuries.
