CALVERT COUNTY, Md. (WJZ) — A Maryland couple was struck and killed over the weekend—and authorities say the woman behind the wheel initially lied to police.

Amy Yensi has more on what investigators say caused the deadly crash.

Her story wasn’t adding up and police soon discovered she had been drinking.

A tandem bike left mangled; an SUV covered with tire marks; a Clarksburg couple crushed and killed. Police arrested the driver, 62-year-old Catherine Lyon.

Charging documents say Lyon told officers she stopped to check on the victims on the side of Tobacco Road Saturday, but later admitted to having a few cocktails.

Relatives say 64-year-old John Fauerby and his wife, 58-year-old Lynne Rosebusch, would often ride together as part of Frederick Pedalers Club.

Bill Smith is the club’s president.

“It just hit me really hard,” Smith said. “We all loved to ride with them.”

Calvert County Sheriff Mike Evans wants Lyon off the road. He’s asking the state’s attorney to ensure “the person not drive a motor vehicle while they’re out on bond.”

Emily Ranson with Bike Maryland says drinking and driving is a danger for the entire biking community.

“There’s nothing a family can do. There’s nothing a normal cyclist can do. There’s nothing an experienced cyclist can do. You’re at the mercy of that drunk driver,” she said.

In Maryland, keeping a safe distance is not just a suggestion, it’s also the law. Drivers here must keep three feet away from bikers at all times.

“This shouldn’t have happened. You know, there are several factors. It was a straightaway. Speed wasn’t very high. People were in bright coloring. This shouldn’t have happened but apparently alcohol was a factor,” said Evans.

Lyon was released over the weekend after posting a $200,000 bail. Her next court appearance is set for January 27.
