BAY CITY, MI — Police have wrapped up their investigation into the recent mauling death of a Bay City mother of four, as the dog responsible and a second dog wait to be euthanized.

Bay City Department of Public Safety personnel on Thursday, Nov. 14, sent their reports related to the Nov. 1 death of Brandy J. Boschen-O’Dell to the Bay County Prosecutor’s Office for review, according to Capt. Caleb Rowell.

Police found Boschen-O’Dell, 41, deceased in her residence at 3212 Westshore Drive in the Westshore Estates Mobile Home Park. An autopsy performed by the Bay County Medical Examiner’s Office determined O’Dell’s death “was caused from several bites made by one or more dogs that were pets,” according to a statement by the police department.

In the home with her were two pit bull-type dogs named Chester and Rocket, and a Chihuahua. Bay County Animal Control arrived and took custody of all three dogs.

Records obtained by MLive via a Freedom of Information Act request show Chester and Rocket were not licensed at the time of the attack on Boschen-O’Dell. The dogs’ owner — who police say was Boschen-O’Dell’s friend — had purchased a license for Chester in September 2017, but that expired the following September. Chester had been 4 years and 10 months old when his owner bought the license.

Craig Goulet, supervisor of Bay County Animal Services and Adoption Center, said there are no records indicating the dogs were adopted from the county’s shelter.

Capt. Rowell said the dogs’ owner has signed over his rights to both dogs. The two are to be euthanized, though the date of this is pending.

Contacted by MLive, the owner declined to speak on the matter, saying it was too soon to do so.

Investigators believe only Chester attacked Boschen-O’Dell, Rowell said. He could not speculate on what sparked the dog’s attack.

“According to (the owner), (Boschen-O’Dell) had no problems handling the dog and he listened to her,” Rowell said. He added that O’Dell had previously told the dog’s owner that Chester had bitten her but told other people an injury she bore was from a box cutter.

Police found no other indication either dog had previously attacked a person, Rowell said. The Chihuahua was returned to its owner shortly after it was seized.

Boschen-O’Dell graduated from Bay City Central High School in 1996.

“Brandy had a very strong personality and would always take care of others, often before taking care of herself,” states her obituary. “She had a compassionate, caring and loving heart for everyone. Brandy loved crafts, gardening, pets, her family and many friends and co-workers at Bob Evan’s and the Stock Pot.”

Boschen-O’Dell is survived by her four children, her parents, a stepfather, her husband, and the dogs’ owner, described in her obituary as her “very special friend and companion.”

Boschen-O’Dell’s funeral was held Nov. 10.
