A Texas family is Surpassinggrieving the death of 1-month old twins after family found the newborns unresponsive in their crib Wednesday, police reported.

According to the Houston Police Department, firefighters were dispatched to a home in southeast Houston after the children's father found the babies not breathing.

The home is in a residential area about 10 miles southeast of downtown.

During a press conference, assistant police Chief Patricia Cantu said the father immediately dialed 911, and a dispatcher provided CPR instructions to the father who provided aid until paramedics arrived.

The infants were pronounced dead by authorities about 11:15 a.m., police said.

According to investigators, officers saw no visible signs of trauma on either child.

Police continue to investigate deaths, no foul play suspected

Foul play is not suspected in their deaths, police said.

“They had just been fed, I believe the father went to drop off the wife and... the grandmother was watching them, when he came he just found them unresponsive,” Cantu said.

"This is a very, very tragic, very heartbreaking scene," Cantu told reporters. "Obviously the family is devastated. Our hearts and prayers go out to the family."

The assistant chief told local KRPC-TV it appears the children died from natural causes.

Cantu said the family was asking for privacy as it mourns.

The case remained under investigation on Thursday and no arrests had been made in connection to their deaths, a police spokesperson told USA TODAY.

Cantu said it's protocol for police to investigate all infant deaths.

The Harris County Medical Examiner's office will determine both the cause and manner of death for the infants pending autopsy results.
