Richardson police released photos Wednesday of a vehicle that could lead to clues to help solve a murder investigation.
Police believe the 2010 black Audi Q5 SUV with the front bumper broken off was used to "dispose" of Jessie Bardwell's body.
Bardwell's boyfriend, Jason Lowe, has been charged with her murder.
Police said they discovered blood and the smell of decaying flesh inside the SUV when they searched the garage of the Richardson apartment the couple shared.
Bardwell remains missing.
"We just want Jessie back," Bardwell's brother Jason Bardwell said. "Jessie didn't have a mean bone in her body."

The latest news from around North Texas.
Dozens of family and friends gathered for a candlelight vigil Wednesday on the beach in Bardwell's hometown of Pascagoula, Mississippi. Family members said the 27-year-old moved to Richardson in December to be with Lowe.
Her father asked Richardson police to check on Bardwell after she didn't call home on Mother's Day.
Police said they need leads to help them search for Bardwell. They hope someone will recognize the damaged SUV that had been covered in mud.
"There's the possibility the vehicle may have become stuck in the mud and somebody may have assisted him," said Richardson Police Sgt. Kevin Perlich.
As police continue their investigation, court records point to Lowe's possible violent past.
According to documents filed in May 2015, he was arrested for aggravated assault after another girlfriend said he choked her to the point of unconsciousness. He "snapped," the girlfriend told police, according to the incident report, and accused her of "cheating and talking to other men."
There are no records showing the case was ever prosecuted.
