Law enforcement is scheduled to release new age-enhanced photos of Robert Fisher who is wanted for the deaths of his family in Scottsdale nearly 15 years ago.
The FBI announced it will join the Scottsdale Police Department on Friday, April 8 at 2:30 to unveil the pictures of what Fisher would look like in 2016.
Fisher is on the FBI's Ten Most Wanted list.
The FBI said Fisher slit the throats of his wife Mary Fisher, 38, and their two children, Brittney, 13, and Bobby, 10, and then blew up the house they all lived in Scottsdale on April 10, 2001.
Fisher is the lone suspect, the FBI said. It's unclear what the motive was or if he might have suffered from mental health issues, according to the FBI.
According to the FBI, Fisher was last seen around 10:30 on the night of the crime. He was reportedly captured on surveillance video driving in his wife's car with the family dog and taking out cash of an ATM. The dog was later found unharmed.
He was added to the Ten Most Wanted Fugitives list in 2002. There have been several tips of possible sightings of Fisher, but none of them panned out.
Fisher is an avid outdoorsman and hunter and it's long been believed he could be hiding out in the mountains or wilderness area.
The FBI is offering a reward of up to $100,000 for information leading to his arrest. Click here for more information from the FBI.
