On Monday, homicide investigators with the Pima County Sheriff's Department began to search for the remains of a 19-year-old man at a property on the far west side.
The sheriff's department was searching for Kristopher Loesch, whose mother and her companion died in a murder/suicide last November.
In November 2008, deputies found the bodies of two women inside of a Dodge Durango near West Mile Wide and North Reservation roads. The women were identified as Tina Rose Loesch and Skye M. Hanson.
An investigation later revealed that the women were wanted in Idaho in connection with the 2000 killing of Tina Loesch's mother, Barbara Loesch. They had been living in a house on the 12000 block of West Daviti Road at the time of their deaths.
Pima County Sheriff's Office spokeswoman Dawn Barkman said the pair likely made a suicide pact after realizing the popular television program "America's Most Wanted" had planned a profile of the murder of Loesch's mother.
Sheriff's deputies later found that Tina Loesch's son was missing.
Born in 1990, Kristopher Loesch was last seen with his mother and Hanson in 2000 in Spokane, Wash. Investigators believed Kristopher had been living in the Tucson area at the time his mother and Hanson were found dead.
Police in Arizona and Washington made unsuccessful attempts to locate him.
"It's almost as if he's vanished off the face of the earth," Barkman said.
Sheriff's investigators spend all day Monday searching for evidence at the property. Nothing was found.
"He could be well and alive," Barkman said. The search was conducted to eliminate the possibility that he was killed and his body buried at the property.
