A father who killed a man suspected of trying to molest his 5-year-old daughter won't face charges, investigators said Tuesday.

Lavaca County Sheriff Micah Harmon said there was no evidence that led investigators to doubt the 23-year-old father's story.

"The Lavaca County grand jury has met today and the Lavaca County grand jury has not returned an indictment," Lavaca County District Attorney Heather McMinn said.

"There doesn't appear to be any reason other than what he told us," Harmon said.

Harmon said the father killed Jesus Mora Flores, 47, from Gonzales, Texas.

Flores was an "acquaintance" of the father who had come to help care for some horses, Harmon said. He did not know how long the two men may have known each other. The girl was taken to a hospital to be examined and has was released, Harmon said.

The father called deputies late Saturday afternoon and told them he attacked a man caught trying to sexually assault his daughter, Harmon said. The father was distraught and asked for medical care for Flores, investigators said.

"This guy was raping my daughter and I beat him up," the father said in the 911 call. "I don't know what to do."

As the father called for help, other family members gave Flores CPR.

The incident happened near a barn in Mt. Olive where some horses were being kept. The adults were shoeing a horse and the girl and her brother had been sent to feed chickens.

The children's grandfather said the boy later came back and said his sister had been taken away by a man. Her father then went out to look for her, the grandfather said.

Investigators said the father went to look for his daughter and called out her name. He then heard her screaming for help, officials said.

The father found both his daughter and Flores partially naked, investigators said.

"In the course of trying to get her away from him, and protect her, he struck the subject several times in the head and the subject died," Harmon said.

Detectives said Flores' pants and underwear were down when paramedics arrived.

Harmon said that all the evidence supported what the father told them happened. He said the father was very remorseful and did not intend to kill Flores.

"They want to move on," the family's attorney said about the situation. "Today they can start their healing process."

The ranch, which is near Shiner, is about 130 miles west of Houston. Killings are rare in rural Lavaca County. Harmon said his office has only investigated six in his eight years as sheriff.
