OGDEN -- Ogden Police detectives booked Jeremy Marshall into Weber County Jail on Monday in connection with a death of a baby.
Police arrested the 35-year-old on suspicion of criminal homicide in the death of Kennedy Lucille "Baby K" Marshall, who would have been 3 months old today.
Charges have yet to be filed in 2nd District Court.
Jeremy Marshall lived in the same home as the girl and her mother, Afton Moneypenny, though he and Moneypenny were not married, said Ogden Police Lt. Tony Fox.
Marshall's bond is set at $20,000.
On the morning of Dec. 14, the Ogden Fire Department responded to the 2600 block of Van Buren Avenue after dispatchers received a 911 call regarding a baby in medical distress.
The infant was taken to McKay-Dee Hospital, then flown to Primary Children's Medical Center in Salt Lake City for treatment. She was placed on life support and died that night around 11:30 p.m. Ogden detectives were notified of the death and opened an investigation.
"Who would murder a sweet baby girl named kennedy," Moneypenny wrote on her Facebook page Dec. 22. She added that her heart is broken.
But hours after Jeremy Marshall's arrest, she wrote that she feels lighter in a way that was hard to describe.
Justice will be served, she wrote. She added that she does not think anyone will post bail for the man she accuses of killing her daughter.
"Mama loves you baby K xoxoxox," she wrote.
Kennedy Marshall was a gorgeous girl with a pure and angelic spirit who loved her pink giraffe, according to her obituary.
Family and friends expressed their condolences to Moneypenny in an online mortuary guest book and on her Facebook page.
"We are so sorry for your loss. Kennedy will always be by your side, walking beside you with your mom and pa. Love you," wrote Shyloe Brunner, of Hooper.
The baby's uncle, Ronald Gailfus, wrote on Moneypenny's Facebook page that he cannot sleep and his niece is all he can think about.
"Uncle rj loves you too baby k... always and forever," he wrote.
In 2004 in 2nd District Court, Jeremy Marshall was convicted of simple assault and domestic violence in the presence of a child, according to court documents.
Moneypenny and Gailfus could not be reached for an interview.
