On Friday, one of the victims was identified as 15-year-old Brooklyn Triplet. Brooklyn’s grandmother, Vanda Triplet, confirmed to CNN the death of her granddaughter. “Brooklyn was an amazing girl. She defended her beliefs and did not keep quiet when she felt wronged.” Triplett told CNN. “She was so funny, witty and smart. Words could not describe the wonderful light she had.” There is a stop sign that regulates the traffic at the intersection where the accident took place and the indicated speed limit for the highway is 50 mph. Witnesses said the Chevy entered the US-377 after making a “rolling stop” at the stop and was hit by the front-left van, which pushed it off the road, according to the report. The truck then veered off the road and stopped on a private road off the highway. The driver of the truck was not injured, the announcement said. The investigation is ongoing and the NTSB, in coordination with the Oklahoma Freeway Patrol, has sent a team of four investigators and a family help specialist to Oklahoma to look into various issues. They will assess highway conditions such as lighting and weather conditions, as well as on-site accident histories and possible causes for human error. They will also look at the vehicle’s compliance with federal and state regulations. Investigators will reconstruct the facts of the collision and analyze the physical elements and damage to the vehicle, the statement said. The group’s work on stage is expected to be completed by Monday and the preliminary report is expected at the end of next month. The full investigation – which will include the possible cause and any contributing factors – will be completed within a year or two. “On behalf of our students, staff, families, and community, I want to thank you for your thoughtfulness, prayers, and encouragement,” said Bobby Waitman, Principal of Tishomingo Public Schools, in a statement. “As we begin the process of broken hearts, I am reminded that our highest priority as teachers is to meet the emotional, mental, social and physical needs of our students. This is our focus right now – and every day we serve students.” , Whitman’s statement added.
