After his daughter's disappearance and Shermantine's arrest, Wheeler said investigators told him she might have been stabbed and killed inside the pick-up truck, but years later her remains were never found. Shermantine vowed to never tell anyone where he buried his victims. The day he was sentenced to death he turned around and looked at the Wheelers and said "at least my parents will know where I'm buried, you'll never know where she is."
Wheeler said he and his wife plan to go to California and pick up the remains, pending the coroner's findings. They plan to cremate their daughter's remains and take the ashes back to their home in Tennessee.
"Friday was the happiest day of my life, a cloud has been lifted from our heads and we'll finally get to bring her home."
Shermantine was convicted of four murders and sentenced to death.
Herzog was convicted of three murders and sentenced to 77 years to life in prison. Years later, an appeals court threw out his first-degree murder convictions after ruling his confession had been coerced and illegally obtained by authorities. He was let go and paroled to a trailer outside the High Desert State Prison in Susanville, Calif.
Last month Herzog committed suicide after receiving a call from Sacramento bounty hunter Leonard Padilla informing him Shermantine agreed to disclose the locations of their victims.
Padilla has been following the "Speed Freak Killers" cases closely and has even worked with a former FBI investigator who interviewed Shermantine while on death row. According to Wheeler, Padilla offered the convicted murderer $33,000 in exchange for him to disclose the locations of his victims' remains. Shermantine agreed to the deal.
Since then authorities have also turned their attention to a third location, not far from where the other remains were found. Shermantine indicated that a possible additional 10 bodies could be found inside a well located at an old cattle ranch in Linden, Calif.
"We've been working non-stop, and we're still there today with all the heavy machinery needed for this type of excavation," Garcia told ABC News. He also said the operation hasn't been easy due to all the debris that's been found and having to be lifted as they continue digging.
"We're committed to stay out here until we find these remains and give closure to the families," Garcia said.
According to an Associated Press report, Shermantine said he wants the money to pay off an $18,000 restitution order that prevents him from buying luxuries like candy bars that inmates with money in their accounts can afford. He also said he'd like to use the rest to buy headstones for his deceased parents.
"He deserves exactly what he did to his victims and should be put to death soon and whatever money he gets he should give it to all the victim's family," Wheeler said.
