The mothers of two missing Dawson County 20-year-old males are making a plea to the community to help find their sons.

Ethelyn Giger and Leann Cox, surrounded by family and friends, spoke Friday afternoon about their sons outside a home on Fredricks Cove in Dawson County.

We are so desperate because we dont know where our children are, Cox said.

David Wood and Mason Cox were last seen at 3:30 a.m. Thursday morning when they decided to go night fishing at Lake Lanier in the Fredricks Cove neighborhood.

Night-fishing is a favorite pastime of the two boys who have been best friends for years, according to their mothers.

He (Mason Cox) had his backpack on and said, Mom, you probably think were crazy, but were going night-fishing. And that was the last time we saw them, Cox said.

Dawson County Public Information Officer Tony Wooten said cadaver dogs from the Dawson County Fire Department were used to canvass near where the two were thought to be fishing. Nothing was found.

A surveillance video given to the sheriffs office by a neighbor shows a vehicle entering the neighborhood at 4:30 or 5 a.m.a time Wooten said coincides with the disappearance.

The mothers said they have no idea what happened to their children.

David and Mason, if you can hear this, call us, Giger said. We just want to hear from our boys.

Right now, Wooten said investigators have no indication of foul play.

Weve been at it for the last 24 hours. Weve left no stone unturned. Right now, were still following up on a few leads, he said.

Wooten did say one of the boys had a cell phone with him, and officers attempted to find the phones location based on its last call. We pinged the phone to see where the last call was made from, Wooten said. Unfortunately it was made shortly after they went fishing. At this point, we believe the phone battery is dead.

Investigators were also not able to find evidence of credit or bank cards being used. Giger said her son, David Wood, didnt have any belongings with him.

My son left his cell phone, his wallet, the shirt he was wearing that nightits all in his room, she said. His car is here. Hes just gone.

Anyone with information about Woods and Coxs disappearance is asked to call 706-344-3636.
