SHERMAN, Texas (KXII) A crash that killed a Fayetteville newlywed couple this weekend is riddled with unanswered questions, and investigators are still working to piece together what happened.
Evan and Sarah Nuessner's car went off the road on Highway 75 near Washington Street, into the culvert, and was swept downstream.
At around 7 a.m. Saturday, police got a call from a family member who was worried about the newlywed couple traveling from Fayetteville, Ark., to McKinney, because they hadn't heard from them.
Sherman police Sgt. Brett Mullen said the couple was last known to be driving through Sherman on Friday around midnight.
"Officers checked local hotels and highways for the subjects but were unable to locate them or their vehicle," Mullen said.
Police got a call a few hours later about a crashed car in the culvert.
When officers got to the scene, they found 26-year-old Evan Nuessner dead inside the car.
His wife, 26-year-old Sarah Nuessner, was nowhere to be found.
Investigators started a large-scale search.
"We went until dark on Saturday and then we resumed Sunday morning and the water had receded some, so the guys were able to get in the water and do more of a bank to bank search," Sherman Assistant Fire Chief, Chris Olson said.
Olson said they divided the area into a grid and left no stone unturned.
Sarah's body was finally found around 11 a.m. Sunday in a five-foot-deep section of Post Oak Creek, four miles downstream from the crash site.
Mullen said investigators are still trying to figure out if weather was a factor.
"It was raining heavily that night, we know that for certain, the culvert was likely full of rapidly flowing water as well, but exactly what caused the crash, that's still under investigation," Mullen said.
It's unknown if the couple had their seat belts on at the time of the crash, and Sherman police are still investigating.
