Little Rock - The parents of KATV's Anne Pressly talked with the Today show's Matt Lauer Monday, five days after suspect Curtis Lavelle Vance was arrested in the beating death of the KATV morning anchor.

Guy and Patti Cannady said while the police were investigating the case as a homicide, there's a lot of evidence that there was more to it than that. They also said there's forensic evidence their daughter was sexually assaulted during the incident, and that she broke her hand fighting off her attacker.

Patti Cannady went to her daughter's Little Rock home after she didn't answer a wake-up call and found the 26-year- old beaten. Pressly died in the hospital five days later without regaining consciousness.

Guy Cannady said the family still has many questions about the murder. He said the police theory is that Pressly interrupted a random robbery, but he isn't convinced of that.

Vance is being held without bond at the Pulaski County jail. He is also accused of raping an east Arkansas school teacher in April.

An arrest affidavit filed this morning in Little Rock District Court shows police believe that several items belonging to Pressly were taken in the attack.

Little Rock police Detective Tommy Hudson wrote in the affidavit that Pressly died after suffering "blunt force trauma" during the attack. Hudson wrote that Vance denied being in Little Rock the day of the attack on Pressly and allowed detectives to swab a DNA sample from his saliva.

The affidavit says it was confirmed "with all scientific certainty" that the DNA found at Pressly's house belonged to Vance.
