Davis was read his rights again Monday, and in the end, visiting judge Mary Bacon found probable cause to continue with the charges.
Prosecutors are alleging that on or before August 4, Davis kidnapped Hightower-Sharp, and stabbed her several times. They say he then heard her kicking after he had placed her in the trunk of his car. So he allegedly pulled over, poured gasoline on her and lit her on fire while she was still alive.
Police say they connected Davis to her murder through DNA evidence found in the trunk of the vehicle that belongs to Davis' girlfriend.
Eyewitness News reporter Jessica Willey confronted Davis at his home recently, and he slammed the door in her face.
Sharp's body was found dumped in the Acres Homes area, where a half dozen other bodies have been found over recent years. Prosecutors say Davis has a lengthy criminal record, which includes robbery, forgery, assault, driving under the influence and weapons charges.
"All we are doing is the investigation at this point," said Davis' attorney, Tyrone Moncriffe. "Investigators will be on this case, interviewing all people, him and those who have made allegations to this point. So at this point, it is just in the investigation process."
"It's a capital murder where the victim, according to the complaint, was killed by being stabbed and set on fire," said Prosecutor Julian Ramirez.
Davis will remain behind bars without bond, and is scheduled to appear in court again on May 7.
