The Oakland County Sheriff's Office says it responded to two drownings within 12 hours during the Fourth of July weekend.

At about 7 p.m. on July 5, authorities received a call about 49-year-old Jason Dwane Brookshire, who went into White Lake on a boat near the 3400 block of Jackson Boulevard in Highland Township and never resurfaced. The Oakland County Sheriff's Office says it's unknown how Brookshire got in the water, and investigators do not believe he was wearing a life jacket.

The sheriff's office's Search and Rescue team, along with the Southeast Michigan Dive Group, actively searched for the man Saturday night. In an update on Sunday, the sheriff's office says Brookshire's body was found late Saturday in 7 feet of water, about 100 miles from shore.

He was pronounced dead after his body was brought back to shore. Investigators believe alcohol was a factor; however, the investigation is ongoing.

The sheriff's office says hours after Brookshire's body was found, deputies responded to a separate incident in Springfield Township.

Authorities received a 911 call at about 4 a.m. on Sunday about 86-year-old Gerald Vernus Bruge, who had dementia and was last seen at 5 p.m. on Saturday. Deputies responded to the home in the 8400 block of Rattalee Lake Road and searched the property, which included a pond. Burge was found about 7 feet in the pond and was pronounced at the scene.

"This has been an extremely busy and tragic weekend for our search and rescue team and our partners," Sheriff Michael Bouchard said in a statement. "Sadly, all the information we had put out in advance of this weekend about ways to stay safe could've prevented these tragedies. I am proud of the skilled efforts that recovered these victims, giving the families closure."
