Martinez great-grandma is charged with murder in baby’s dog-mauling death

Migdelia Guadalupe

Date: March 25, 2022

Columbia County authorities have filed second-degree murder charges against the great-grandmother of a baby who was viciously mauled by a family pet on Tuesday morning.

Migdelia Guadalupe, 56, was “under the influence of drugs” when caring for 7-month-old Serenity Garnett and was “unable to render aide to her during the dog attack,” according to a warrant.

This photo of Serenity Garnett appeared on a GoFundMe page that raised over $15,000 for her funeral.

Investigators also found Guadalupe in possession of 0.5 grams of meth and about 1.0 grams of liquid meth, according to a warrant for meth possession.

Paramedics were called to 3701 Columbia Dr. in Martinez on Tuesday morning for an attack by the American Bulldog/Pyrenees mix. Guadalupe had been bitten on her arms, and the baby was not breathing from several bites and puncture wounds, a sheriff’s report says. Both went to Augusta University Medical Center, but the child died.

This picture of the American Bulldog/Pyrenees mix appears on the Facebook page of the dog’s owner, Donna Mills.

Guadalupe was released from the hospital Friday and arrested after the investigation revealed she was high at the time of the attack. She is being held without bond at the Columbia County Detention Center.  

Sheriff’s Maj. Steve Morris said the child’s grandmother had dropped the baby off at Guadalupe’s rental home at 3701 Columbia Dr. in Martinez. Guadalupe is the victim’s great grandmother.

“The K9 belongs to Donna Mills, who splits ownership of the residence with her brother, Danny Mills,” a sheriff’s report says. “Ms. Mills is incarcerated at this time.”

The baby’s mother, 18-year-old Mercedie Rivera, arrived before paramedics left the home and followed them to the hospital. She is listed in a report as a student at Harlem High School.

A Facebook page for Donna Mills features multiple photos of the pet, which remains under quarantine and will likely be euthanized after the 10-day period is over.

Also, a GoFundMe page to raise funds for Serenity’s funeral raised $15,000 of a $10,000 goal.
