New Mexico's father was arrested on Friday night and accused of having beaten his daughter to death after she told him that she did not want to do homework.
Brandon Reynolds, 36, from Albuquerque, was accused of ill-treatment with a child, deliberately causing the death of a child under 13, the police said.
Father said that he began to splash the girl when she refused to do her homework around 8pm Thursday before he eventually "blacked out," according to a criminal complaint received by the Albuquerque ABC branch of KOAT.
Reynolds did not call 911 at noon at 1 o'clock in the morning and said that his daughter suffered from heart failure, according to the police.
"When they came to the rescue, they realized that it was turning into a criminal situation, and they called us and we took the investigation," Albuquerque spokesman Al-Bakerke stated at a press conference on the eve of this week. "AFR acknowledged that this did not correspond to what they were talking about and this became a criminal investigation."
Emergency reagents tried to revive the girl as she was taken to a hospital in the University of New Mexico, where she was declared dead.
"The detectives learned from the hospital staff that the girl was seriously injured," said Michael Guyere, Chief of Police in Albuquerque. "Detectives from our crime against children were summoned to the scene to investigate with our murder department."
The New Mexico Department of Children, Youth and Families (CYFD) was also called to investigate abuses.
According to the complaint, the officers found blood on the walls of the living room and carpet when they arrived. The complaint states that the girl was repeatedly hit by a boot and covered with bruises when the authorities came home.
"This is certainly a dramatic tragedy, and our officers and detectives are working diligently to get justice for this little girl right now," Geyer said.
Reynolds is held at the police station.
The police said that there were no other children in the house when Reynolds allegedly killed his daughter, and the CYFD had no history in the house.
Reynolds had exclusive responsibility for her daughter after a court dispute with her mother, according to Albuquerque. He was given the custody of his daughter after worries were raised about the use of mother's marijuana.
