The killing of a 90-year-old man whose body was found tied up in his ransacked rural home on April 11 remains under investigation, but there is no new information to release to the public, the Carver County Sheriff's Office said Wednesday.

There are no new leads in Earl Olander's death, which was ruled a homicide last week, Chief Deputy Jason Kamerud said.

At a news conference last week, Sheriff Jim Olson said that Olander's hands were bound and his face was slashed and bruised. More than one assailant was probably involved, Olson said.

A precise cause of death still has not been released. The Sheriff's Office has received a preliminary autopsy report, but intends to wait for the final report before releasing any information, Kamerud said.

The department is also waiting on data analysis and DNA test results from the Minnesota Bureau of Criminal Apprehension.

"We are continuing to follow up on the available leads," Kamerud said, adding that tips are still coming in to the Sheriff's Office.

Olander's death occurred sometime between the afternoon of Thursday, April 9, when he was last seen stopping by a neighbor's house, and the afternoon of Saturday, April 11, when his body was found by neighbor Jerry Scott.

His funeral was held Monday at his longtime church, East Union Lutheran, near Carver.

Olander, a lifelong bachelor who had lived in his rural family home for nearly his whole life, had many friends and no enemies, his pastor and many neighbors said in the days after his death.
