The UPS package handlers killed in an accident at the company’s hub at Ontario International Airport were identified Wednesday, Nov. 27.

Austin Stache, 20, of Rancho Cucamonga, and Noe Tinoco Jr., 22, of San Bernardino, died Monday, the San Bernardino County Coroner’s Office said.

They were driving and riding in what is known as a tug, a vehicle that pulls dollies that are loaded with packages to and from airplanes. The UPS facility at the airport sorts and distributes packages for air and ground delivery.

The accident happened sometime before dawn Monday. A widely circulated photo on the internet shows the tug upside down.

Luke Brown, a spokesman for Cal/OSHA, which investigates workplace accidents, said the tug turned over and crushed the men.

A GoFundMe page established to benefit Tinoco’s family said Noe Humberto Tinoco Jr. was “a son, a brother, a cousin, a nephew and an inspiration. … Noe loved two things in this world the most: his family and baseball,” especially the Dodgers.

Brown said he could not yet comment on the cause of the accident. The report on the investigation will not be released for four to six months, he said, and will include a narrative on the cause.

The report will note whether UPS was cited. Companies are allowed to challenge citations and fines. People who say they are UPS employees have speculated on the cause of the accident but have not agreed to be interviewed by The Press-Enterprise.

The tug that crashed does not have a top, while some UPS tugs enclose the operators. UPS spokesman Steve Gaut said Wednesday that topless tugs are typically used in areas where there is more favorable weather.

Witnesses to the crash received one-on-one counseling Monday, Gaut said. Group counseling was offered to others.

When such an accident occurs, UPS safety officials address it throughout the company.

“We try to be respectful such that … we need to give people time to reconcile the situation but then we will address it across the network, learning what we can from the accident,” Gaut said. “That will happen in due course.”
