Reward offered...

Since Sonoma County investigators have cleared Nicholas Scarseth of any involvement in the murders of Jason and Lindsay, they have now secured a reward for the capture of those responsible/involved...

Authorities announced they had secured a $10,000 reward from Carole Sund/Carrington Memorial Reward Foundation to help break the case.

"We need to find the person or persons responsible for this heinous act and get them off the street," said Kim Petersen, the executive director of the foundation.

Police have also apologized to Nicholas Scarseth and his family for their very public accusations that he was their prime suspect or "person of interest"...

Also Wednesday, police announced they had cleared Nicholas Edward Scarseth, 21, a day after he made himself available to investigators and was described as a "person of interest."

Edmonds said Scarseth passed a polygraph test.

"He was cooperative, and was released after our interview," Edmonds said. "We presently do not view Mr. Scarseth as a suspect."

Scarseth's parents said two Sonoma detectives showed up at their house in Chippewa Falls, Wis., to apologize for naming their son in a police alert. As it turned out, the tip that led detectives to their son came from a person who reported seeing the couple after their bodies were already in the morgue, they said.

"It turned out to be a complete case of mistaken identity," Mark Scarseth said. "He is not the guy they were looking for."
