Delgado reportedly parked his tractor-trailer at a chemical plant in the 300 block of Joe Frank Harris Parkway or Highway 41 in Emerson — a town near Cartersville. Employees told police the man was acting erratic before the incident happened. Police said Delgado was under the influence of a mind-altering substance at the time of the wreck.
Delgado, 52, of Rome, N.Y., was arrested and charged with DUI, involuntary manslaughter, vehicular homicide and reckless conduct, police said.
“The brakes, the parking brake on the vehicle was either not set or failed causing the vehicle to become unsecured and rolled down the hill, striking the red truck as it was traveling northbound on Highway 41,” Emerson police Chief Stan Bradley said.
Emergency crews worked for about two hours to extricate the family after the 9 p.m. crash. The tractor-trailer spilled hazardous materials onto the highway, slowing the process of removing it, according to a press release sent Friday afternoon.
