A Daniel Webster High School student was killed Monday, Nov. 9, when a Tulsa Public Schools Suburban collided with a semi-truck on the Turner Turnpike in Lincoln County.

The crash happened around 12:45 p.m. near mile marker 170, close to Chandler, according to the Oklahoma Highway Patrol. The semi-truck was entering the turnpike from a travel plaza when the collision occurred, KJRH reported.

The group was returning from the Oklahoma Association of Student Councils State Convention in Norman, according to Tulsa Public Schools.

One person was ejected from the Suburban, and one person was pronounced dead at the scene, according to KRMG. KTUL reported it was not clear whether the person ejected was the student who died. A few of the students were trapped and had to be extricated. The semi-truck driver was not injured.

OHP Lt. Mark Southall told KRMG there were seven people in the SUV and only the driver in the semi-truck.

"We don't know how the collision took place at this time. We are still in the early stages of the investigation," Southall said.

Tulsa Public Schools said in a statement that seven students and one staff member from Webster High School were in the vehicle. The students were juniors and seniors. KTUL reported five were seniors and two were juniors.

The accounts differ on how many people were in the Suburban. OHP told KRMG seven people total were inside, while TPS said the vehicle carried seven students and one staff member.

Everyone in the vehicle other than the student who died was taken to Tulsa-area hospitals, KJRH reported. The Oklahoma Highway Patrol said several were in critical condition.

The student's name has not been publicly released.

TPS canceled its board of education meeting scheduled for Monday night. The district said in its statement that support counselors would be stationed at the west Tulsa school beginning Tuesday, Nov. 10, according to the Tulsa Flyer. Family & Children's Services will also be on site.

The district directed families needing immediate help to contact COPES, a 24-hour crisis line, at 918-744-4800.

Tulsa Mayor Monroe Nichols released a statement on the crash.

"My heart breaks for the families who are grieving, those sitting in hospitals right now receiving updates on their loved ones, and the Webster school community," Nichols said.

The wreck shut down the eastbound lanes of the Turner Turnpike. OHP diverted traffic at mile marker 168, Public Radio Tulsa reported.

OHP continues to investigate the cause of the crash.
