Man Missing Since Saturday Night; Search Resumes Monday

"The longer the search drags out the worse it gets because even though you want to hope deep down, you know he's not coming back," said the victim's wife, who does not want to be identified.

She told 7NEWS, she, her husband and their children were watching the sunset when the boat's anchor became stuck in mud on the bottom of the reservoir. Her husband went into the water to try and free it and never resurfaced.
