Ryan Mosholder, 25, was arrested at a Newark residence a few hours later and booked in the Licking County Jail on a felony murder charge in the death of Bri'anna Mosholder.
"He is the sole focus of our investigation," Heath Police Chief Dave Haren said Tuesday.
The baby's body was found covered in bruises, with blood coming out of her nose and mouth, according to court documents.
A couple of hours beforehand, Mosholder sent a text message to his brother "indicating that he had done something unforgivable and was going away for a long time if the police were called," according to documents.
He fled the scene before police arrived, leaving two other children in the apartment with his brother, Haren said. The children's mother was away from home attending a work training session at the time.
Mosholder told officers that he hit the infant, but said he did so after she had died, according to documents. Relatives also "disclosed that they had previously seen the suspect be rough with the infant, including hitting the baby with an open hand when the infant was laying face down," according to documents.
Mosholder was arrested at the Cherry Street home of his father and stepmother, the same residence where a Newark man was shot and killed during a January break-in. There are no connections between that incident and Bri'anna Mosholder's death, Haren said.
Mosholder does not appear to have an adult criminal record in Licking County, but he was charged in 2009 as a juvenile after stabbing and repeatedly punching and kicking someone in a fight at Newark park, according to court documents.
