Authorities have identified the elderly male who was found Thursday in a shallow grave as 72-year-old Roger Knickerbocker II.

Two suspects have gone before a judge in connection with the man's death.

Daniel Olar, 20, from Pontiac, is charged with open murder, and Christopher Grinnell, 24, from Bay City, is charged with accessory to a felony after the fact in the death of Knickerbocker.

MSP Lt. Dave Kaiser said Olar and Knickerbocker knew each other for several years because they had both previously lived in Pontiac.

Knickerbocker was a registered sex offender. He was convicted of first-degree criminal sexual conduct with someone under 13 in 2000 in Pontiac.

Police said an MSP cadaver dog indicated on a shallow grave in the 5800 block of Snyder Trail in Hale during an investigation that stemmed from an unrelated arrest that happened Wednesday night.

Police said they arrested a female on a domestic violence count Wednesday when she told police she knew two people who were "getting away with murder." 

"She became upset that she was getting arrested and that two people who had done a recent murder were getting away with it. She told us it was an unreported homicide," Kaiser said.

The woman described the murder scene to police, which is where the cadaver dog indicated there was a shallow grave.

Police looked inside the home and saw evidence of a brutal crime with a lot of blood, Kaiser said.

"Inside the house was a crime scene of a very violent crime. A lot of blood splatter. A lot of it had been cleaned up," Kaiser said.

That is when police brought in the cadaver dog who hit on a grave behind the home. The gravel was soft and appeared to have been dug up recently.

"This crime may have never been discovered. It did not happen last night. It actually happened quite some time ago," Kaiser said.

Police started digging about 6:30 p.m. Wednesday night and continued digging on Thursday.

"I thought it was crazy for that to happen here up north. I'm from Detroit. I'm used to hearing about it down there, but not up here," said David Williams, Hale resident.

Hale is located in Iosco County.
