South Lake Tahoe police Chief Terry Daniels said the 27-year-old murder of Richard Swanson will be re-examined.
Swanson was killed in August 1980 during the robbery of a gas station where he was a clerk. Swanson suffocated on his gag. The murderer escaped.
Daniels, as well as Sgt. Jeff Regan, who is assigned the case, were tight-lipped about the renewed investigation.
"We've made some huge inroads in it," Daniels said.
Swanson was awaiting his junior year in high school when he was killed. His parents, Ron and Sharon Swanson, moved to Sonora, Calif., after their son's murder but traveled to South Lake Tahoe last month to plead to the City Council to reopen the case.
"It is time to properly investigate this horrendous crime," Ron Swanson said at the time. "We will no longer be silent victims."
