RED BLUFF, Calif. -

At a press conference Saturday evening in Red Bluff, National Transportation Safety Board officials unveiled a series of findings from the investigation into the fiery crash Thursday on Interstate 5 in Orland that killed 10 people and injured dozens of others.

Included, evidence which shows no effort to brake along the path the FedEx tractor-trailer traveled before crashing head-on into the tour bus carrying high school students and chaperones to Humboldt State University.

"There are no tire marks," said NTSB board member Mark Rosekind. "So this is just the truck tractor, it's leaving the southbound lane at 10 degrees, across the median into the northbound lanes. There are no tire marks anywhere."

It was also revealed Saturday that the driver of a white Altima struck just before the tour bus saw flames coming out of the trailer or front portion of the truck.

The driver of the FedEx tractor-trailer has been identified by the Sacramento Bee as 32-year-old Tim Evans.

Evidence is also starting to reveal how the bus driver, Tala Salanoa, attempted to avoid the crash. The NTSB found 145 feet of brake marks caused by the bus before impact. Those marks indicated the bus had made a turn to the right, away from the oncoming tractor trailer. Salanoa was among those killed in the crash.

Also killed were five students out of Southern California: Marisa Serrato, Adrian Castro, Denise Gomez, Ismael Jimenez and Jennifer Bonilla. They were on their way to tour Humboldt State and meet faculty. All were low-income students who had been accepted to the university.

Three chaperones on the bus were also killed. They are Michael Myvett, his fiancee Mattison Haywood, and HSU counselor Arthur Arzola.

Among the information revealed Saturday by the NTSB is that the tour bus was basically brand new - a 2014 Setra equipped with lap and shoulder belts.

Some of the victims who died were ejected from the bus.

"We're going to look at whether seat belts might have kept them in their place if that would have made a difference in the survivability of this accident," Rosekind said.

Rosekind said "black-box" type recording devices were on board both vehicles, although it's unknown how much information was kept on the one in the bus.

Unfortunately for investigators, the device on the FedEx truck was destroyed in the crash and fire. The NTSB instead will be looking at the semi-truck's transmission to determine what gear it was in at the time of the crash, which will hopefully give them some kind of idea of how fast it was traveling when the accident happened.

The CHP has also provided blood samples of both drivers, which are on their way to be tested in Oklahoma City. They will be tested for evidence of alcohol, prescription or illegal drugs and smoke.

The NTSB is still asking anyone who witnessed events leading up to or the crash itself to contact them with any information, pictures or video. The NTSB can be contacted by email at witness@ntsb.gov or by phone at 202-557-1537.
