ORLANDO, Fla. -- Upgraded technology could have saved the life of a 19-year-old woman who was abducted, raped and killed last week.

William Davis was questioned by Orange County deputies a week before investigators believed he killed Fabiana Malave.

Davis gave deputies his name and fingerprint, but deputies did not realize he was a fugitive.

Investigators said Davis confessed to murdering Malave in his Pine Hills home, the same home where he slipped through deputies' hands a week prior. Davis is accused of abducting Malave from her job at a Sanford car dealership.

Deputies said they knew something was not right when they spoke to Davis during a sweep for probation violators, but could not find a reason to arrest him.

Davis was confronted by an Orange County deputy, three Orlando police officers and a probation officer. They checked his finger prints, but the system only reads from the Orange County corrections system, not the Florida Department of Law Enforcement's statewide system.

If Davis' prints had been run through the FDLE system, the officers would have known Davis was wanted for violation of probation in Polk County.

Orange County said it is in the process of changing the system now.

"We are attempting to secure the funds so we can be hooked into the system," Capt. Angelo Nieves of the Orange County Sheriff's Office said.

Polk County Sheriff Grady Judd said the killing would have never happened id Davis had been kept in prison for his entire sentence instead of being paroled early.

"It's frustrating to anyone because he was let out on parole and then skipped probation in a move, and it would have been next to impossible for Volusia, Orange or Polk to find him if we didn't have an address," Judd said.

The officers who found Davis could not have pinpointed his identity through the National Crime Database or the state's database because he gave a fake birthday, but he would have been found if the officers had used their laptops and put Davis' name into the Department of Corrections Web site. Davis would have shown up, along with 17 other men with the same name, complete with his picture and his status as a fugitive.

The Orange County Sheriff's Office has nearly 200 portable fingerprint devices and they hope to have access to the state's database soon.
