Friends Remember Perinton Woman Killed in Accident

Twenty-two-year-old Mark Scerbo is now facing manslaughter charges in the death of Heather Boyum.

Monroe County Deputies say he was doing "wheelies" on a motorcycle behind a car his girlfriend was driving when he drove onto the shoulder and knocked Boyum off her bicycle.

It happened just before 8:00 Sunday morning on Route 250 in Penfield.

Friends, family and co-workers all say the same thing about Boyum; that she was passionate in every aspect of her life. She was a fierce athlete, a motivated teacher and a dedicated mom.

A memorial now stands where 40-year-old Heather Boyum was knocked off her bicycle and killed Sunday morning in Penfield.

Witnesses found her just moments later. Scott Thompson happened to be driving by on his way to scout out spots for deer hunting.

He rushed to Boyum's side to check her pulse and try CPR.

He said "I have a wife that's 40, and two young boys at home. I was thinking, 'If this was my wife, I would want somebody to do everything they could for her'...I stayed around and I actually did it with the ambulance crew. And I continued to do compressions with the crew. And that was all that we were able to do for her."

Boyum's friends say she was on the type of ride she'd done many times before, early in the morning, before her children woke up.

Close friend Gretchen Stahlman added "She had just gotten that tri-bike and she was so excited because it was really gonna take her, really gonna bump up her game.

Stahlman is a member of Rochester Mom's in Motion. Boyum joined just over a year ago, and fit right in.

The group celebrated a major milestone the night before Boyum's death. Boyum had just finished a Half Ironman challenge in an incredible time, just under 6 hours.

It was just one of many of Boyum's accomplishments. She had her Master's Degree from the University of Rochester, was an accomplished teacher, swimmer and diving coach, as well as a devoted wife and the mom of two young children.

 "There was a saying that she had on her Facebook page that life is precious, you should treasure every moment," added Stahlman. "And so that's what I think we should be doing, in her memory, is treasuring the moments."

Boyum taught biology at Fairport schools for ten years. Superintendent Dr. Jon Hunter says more than 300 students came out to the high school to console each other, Sunday night.

A crisis team will be on stand-by to counsel students and staff this week.

A committee is putting together a memorial for Boyum at the school; they hope to have it up by the beginning of the fall semester.
