WEATHERFORD (CBSDFW.COM) – The search for a 10-year-old boy who fell into the Brazos River continues Monday in Weatherford. Boats are expected to be back on the water throughout Memorial Day in what crews are now calling a recovery effort.

According to rescue officials, the child was fishing with friends on Saturday when he fell into the river. Some other boys tried to rescue their friend, but could not locate him. And then, despite the use of sonar, water rescue dogs and several search boats, crews have also come up empty along a four-mile section of the river at Horseshoe Bend.

That search has since been expanded to as much as 10 miles from where the child went into the water.

The boys were unsupervised and not wearing life jackets, emergency officials added. At this point, the child is presumed to be dead. His family has requested that his name not be released.

The rescuers on Monday are hoping to bring closure to the boy’s family. “It’s frustrating that we have the family here and they need some closure, and we haven’t been able to give it to them yet,” said Battalion Chief Donald Schauer with Parker County Emergency Management. “But we’re going to keep trying the best we can to do that.”

Unfortunately, there is not much more that searchers can do other than cling to hope and retrace steps. “Talking to the family, we can give them some real closure by completing the mission that we came out here do to,” said Capt. Randy Ingram.

Crews plan to be at the river from 8:00 a.m. to 7:00 p.m. for however many days it takes to find this child.
