UPDATE: Newaygo County double homicide,suicide: Answers elusive for survivors

NEWAYGO COUNTY, MI -- In a graphic 911 call, Marcia Hoover is breathless and clearly in distress as she tells a 911 dispatcher that her husband is about to shoot her.

"He's coming after me. He's going to shoot me," Marcia Hoover yells to the dispatcher on Wednesday, April 10.

Second later, she says, apparently to her advancing husband: "In the name of Jesus, in the name of Jesus."

Then, there are no sounds from Hoover or anyone.

The 911 tape of what police say was a double homicide then suicide -- Marcia Hoover, 62, and the couple's 37-year-old son, Charles Isaac Hoover were shot to death allegedly by 59-year-old Charles Mark Hoover -- was released by Newaygo County sheriff's officials today.

The shootings are believed to have happened about 1:45 p.m. at the Hoover's home at 13662 N. Goldfinch Trail near Bitely.

The 911 recording is extremely graphic, but is one of the few clues police have in the ongoing investigation as to why the husband committed the act.

Marcia Hoover and the son were found dead just outside the home, while Charles Mark Hoover was discovered inside the residence by Michigan State Police robot sent inside to minimize any danger to officers.

Newaygo County Undersheriff Brian Boyd said Charles Mark Hoover's motivation may never be known.

"We may not get the answers we want. The people that saw him every day are dead," Boyd said.

In the 911 call, Marcia Hoover's voice wavers and she's out of breath in apparent fear and panic.

"We need help. My husband has just shot my son," she says. "Please, we need an ambulance. He's ready to shoot me now."

In the recording, she tells a dispatcher that her husband has a handgun. Moments later, she says that he's coming after her.

"He's coming after me. He's coming after me. He's got the rifle now," she yells, clearly in distress.

Boyd said some people who knew Charles Mark Hoover described him as a religious fanatic who sometimes talked about the world coming to an end.

He stockpiled food, dry goods and canned goods,in the compound-style property, police confirmed.

The property includes at least four buildings and at least two of those had living quarters. The was no large cache of weapons found, Boyd said.

"We've heard from some that he was a very kind person, that he wasn't violent, that he was a religious fanatic," Boyd said.

"Most of the time, when something like this happens, the people committing the crime have some history with the police," he said. "But this individual was not someone we were familiar with."
