At the Dad's Club of Pearland, balloons and teddy bears filled the baseball field. A memorial has been growing since the boy went missing at the Pearland home, located in the 6700 block of Fite Road, where he was spending the holidays. McGhee was visiting with his family from Connecticut.
Volunteers searched the city, from parking lots to the woods, hoping for a different outcome. Dive teams had previously checked the pond, but didn't find him.
A Pearland family cut their holiday short and drove back from Brownsville to help in the search.
"I said, 'Dad there's a missing child.' He couldn't sleep, he kept pacing back and forth," Mario Esquivel Junior said. "He said, 'Let's go check.'"

"I feel so bad, but we had a lot of support in this town. I have never seen so many people. It looks like a hurricane is coming, so much help," Esquivel Junior added. "Everybody pitched in."
McGhee is the relative of former NBA star Marcus Camby.
