OGDEN -- Jeremy David Marshall told police he accidentally struck 3-month-old Kennedy Lucille Marshall's head on a crib "with substantial force," according to a probable cause statement in his case.
Marshall, 35, was jailed Monday on suspicion of criminal homicide in the Dec. 14 death of the infant.
Marshall made an initial appearance Wednesday morning in 2nd District Court, where prosecutors continued his hearing to today for filing of formal charges.
The homicide charge is the first in the city since January 2010, according to Ogden Police Department records.
The probable cause statement was signed by Ogden Police Detective Lane Olson at the time of Marshall's arrest Monday as part of the Weber County Jail booking process.
Olson wrote: "Jeremy Marshall's 3-month-old stepdaughter was transported to McKay-Dee Hospital due to unresponsive behavior. The child was examined in the emergency room. The child had brain injury consistent with non-accidental trauma.
"The child was transported to Primary Children's Hospital. The child was pronounced dead at Primary Children's Hospital. Primary Children's Hospital confirmed the child's injuries were non-accidental.
"Marshall told family members he caused the death of the child.
"Marshall told me he had struck the child's head on the crib with substantial force but it was accidental."
Emergency medical personnel were summoned to the child's home in the 2600 block of Van Buren Avenue the morning of Dec. 14 after a 911 call about the injured child, police said.
The infant was flown from McKay-Dee Hospital in Ogden to Primary Children's Medical Center in Salt Lake City, where police said she died about 11:30 p.m. the same day.
Marshall does not appear to have an extensive criminal record, according to court records.
However, he does have two divorces in Utah that coincided with protective orders filed against him by the wife in both cases, with one order still in effect, according to the state court database.
Marshall has a 2004 conviction in Ogden for simple assault and domestic violence in the presence of a child and a 2009 misdemeanor theft conviction in Layton.
Marshall is being held in Weber County Jail on $20,000 bail.
