SAN ANTONIO -

Jonathan Moya, an Olmos Park man who was arrested on a charge of injury to a child, now denies slapping his 18-month-old son in the face, causing bruising.

The statement is in contrast to a reported confession that the 18-year-old made to San Antonio police detectives last week.

According to an arrest warrant affidavit, Moya was questioned by detectives Friday after his son was rushed to Christus-Santa Rosa Children’s Hospital.

Police found bruises on both sides of the baby’s face, and did not believe Moya’s initial story about the child falling out of a crib, the affidavit stated.

Later, under questioning, Moya reportedly told investigators he did, in fact, cause the injuries.

He said he was frustrated by the fussy baby and slapped his son in the face “for about five minutes,” the affidavit stated.

However, it’s a story Moya now denies.

"I just told them a lie -- that I hit him -- because they said, ‘You're not going to be able to get out of it.’ So I told them I hit him,” Moya said. “I just don’t know how it happened. I wasn’t even in the room. I was getting his bottle."

Moya spoke to KSAT 12 News Monday morning after his weekend arrest and subsequent release from the Bexar County jail.

The baby, who he identified as Jonathan Jaedyn Moya Jr., has since been placed in the care of another relative,” he said.

The teen said he has been working hard to provide for Jaedyn -- as he’s known to relatives -- and his growing family.

Moya and his girlfriend are expecting a second child.

Right now, though, he said his mind is on finding a way to see his first child again, and clearing his name.

"I can't sleep. I can't do anything without thinking about him," Moya said, through tears. “I wouldn’t do anything to hurt him.”
