Two MSU students are dead after separate incidents over the summer.

Then-human biology junior Michael Carter and then-chemical engineering sophomore Meghan Beedle both died in July.

Carter, 19, died sometime between 8 p.m. July 4 and 8:30 a.m. July 5 after suffering from hypothermia and drowning. Eighteen-year-old Meghan Beedle died on July 30, from complications of mononucleosis.

Carter had been spending time with his girlfriend, 18-year-old Kerry Melenovsky, and three other friends at a cottage near Lake Huron in the thumb-area over the Fourth of July weekend.

Both Carter and Melenovsky, who had been dating for more than three years, were passengers on a personal watercraft operated by 18-year-old Lyndsay McGarry in the water near Caseville and Port Austin.

The trio entered the choppy water between 7 and 7:30 p.m., according to Richard Koehler, a detective with the Huron County Sheriff's Office.

"It was probably somewhat inviting for them when they saw the waves," Koehler said. "They went out about a mile off-shore, where they were swamped, overturned by a large wave."

All three teenagers were wearing flotation vests and were not injured, but the personal watercraft would not start again after being turned upright again.

After attempting to swim against the current and 15 mph winds, while pulling the personal watercraft behind them, Melenovsky and McGarry decided to swim to shore while Carter remained with the vessel about a half-hour before sunset, according to Koehler.

That was the last time the women saw Carter alive.

"The two girls made it to shore and reported their friend was still out there," Koehler said.

The Huron County Sheriff's Office Marine Division and U.S. Coast Guard searched for him, but were unsuccessful.

At 8:39 a.m. on July 5, a woman reported to authorities she had found a body floating along the shoreline about four miles east of where the trio left shore. The body, which still had the vest attached, was identified as Carter. The personal watercraft was found earlier at a separate location by the Coast Guard.

An autopsy revealed Carter had drowned after succumbing to hypothermia in the cold water.

Carter's sister, Nicole, 21, said her family was shocked to hear the news. "It was very hard. I really loved him and he was a caring person," she said.

Nicole said she and her relatives will miss her younger brother.

"We were a very close family," she said.

Meanwhile, Beedle died on July 30, from complications of mononucleosis.

"We were very shocked. Everybody was," said Bradley Beedle, her father.

Bradley Beedle said his daughter, who had cystic fibrosis, called home from her internship at Walt Disney World in Orlando, Fla., because she felt sick.

"She said she had a cold or something and we convinced her to go to the doctor down there," Bradley Beedle said. "He said, 'Oh yeah, you've got mono.'"

Her family had her flown back to Michigan and immediately alerted doctors, including members of a cystic fibrosis unit at MSU.

Meghan Beedle, who would have been beginning her second year at MSU this fall, arrived back home July 29. She died the next day at the Clarkston branch of the Pontiac Osteopathic Hospital.

Richard Honicky, a doctor in MSU's College of Human Medicine, said he wasn't surprised to learn of Beedle's death, and offered possible explanations as to what complications might have arose.

"Cystic fibrosis is a life-limiting disorder, the median age of survival is 32," Honicky said.
