Franklin County's new underwater search and rescue robot has been put to use in Grant County to look for a Moses Lake man missing since December.
The SARbot was used to search the Potholes Reservoir on Thursday, which is near where Dan Toya's unoccupied, locked truck was found Dec. 23.
Toya, 64, apparently went missing while taking his dog for a walk near Samson's Beach. He was reported missing by his wife after he failed to return home with the family's 10-month-old golden Labrador retriever.
Toya said he was taking Molly for a walk after leaving a Moses Lake veterinarian's office.
A side-scanning sonar boat from Boise searched the reservoir in the days after Toya went missing, but nothing was found.
Sheriff's officials said the SARbot "worked well" but Toya was not found. Deputies plan to use the SARbot again.
Franklin County sheriff's officials and coroner worked for two years to raise enough money to get the remote-controlled search and rescue robot to help with water rescues.
Four deputies began training on the SARbot on Feb. 13, and a few days later, it was used to search for passengers in a submerged vehicle in north Franklin County.
