One child is dead and another is hospitalized following a tragic accident at a Somervell County retreat center Thursday.

Both victims are six-year-old boys who were visiting Camp Arrowhead, located northeast of Glen Rose on CR 199, with a church group, according to Chief Deputy Darrell McCravey with the Somervell County Sheriff's Office.

"There was a group of folks - all Seventh Day Adventists from all over the United States and others who we believe to be from outside of the country - attending a retreat at the facility," MCravey said. 

According to the report, there were about 20 to 25 kids in the swimming pool and a number of adults around it when things started to get "a little bit rowdy."

"There were a lot of the kids in the shallow end of the pool playing basketball," McCravey said. 

In the midst of the commotion, supervising adults started counting the number of children in the pool and realized they could not account for at least one child. 

"At that time, they located one young man at the bottom of the pool in about five feet of water close to the slide," McCravey said.

An adult immediately dove in to remove the child from the pool and began performing CPR.

The horror intensified when it was determined another child was also "down in the pool," McCravey added, saying the second child was extracted from the pool and attempts to save his life ensued. 

"A short time later, an ambulance arrived, and the first child rescued from the pool began coughing up water and was somewhat breathing," McCravey said. 

That child, believed to be from Dallas, was transported to GRMC by ambulance and later flown to Cook Children's Medical Center in Fort Worth.

"I understand he is in stable condition and things are looking good for him," McCravey said. "But they were never able to resuscitate the second victim."

The deceased, a resident of New York, was reportedly attending the retreat with an aunt and uncle.

"This is a horrible thing for this family to be going through," McCravey said. "It's horrible for the whole church group. It was just a horrific accident."
