The Ector County Clerk's Office tells Big 2 that Linda and Jose Ariaza filed a civil suit against Nicole Sheesley on September 27th.
The civil suit comes months after the May 29th fatal crash in northern Ector County.
Texas Department of Public Safety troopers say that Ariaza, 62, was driving a minivan on U.S. 385 north of Odessa when she slowed down to make a U-turn.
Ariaza was reportedly planning on turning around to deliver a spare tire to a disabled vehicle on the other side of the road.
However, Sheesley -- who was driving a pickup truck -- reportedly rear-ended the minivan with a pickup truck.
The impact from the crash tore off the back of the minivan.
Three children in the minivan -- 4-year-old Alaina Elvita Belis, 11-year-old Jamie Marie Belis and 8-year-old Ruben Julius Belis -- were pronounced dead at the scene.
All 3 children were from Seminole.
Ariaza, 26-year-old Madonna Belis, and 29-year-old Carlos Osvaldo Amaton were all rushed to Medical Center Hospital after with varying injuries after the crash
All three adults -- who later recovered from their injuries -- were in the minivan at the time of the crash.
Sheesley wasn't injured in the crash.
An Ector County grand jury decided not to file charges against anyone for the crash on September 11th, even though there was evidence that both drivers were at fault
