The 64-year-old man who police say died at the hands of two fugitive teens in British Columbia — also sought in connection to the death of a tourist couple — was a university lecturer and father-of-two who loved nature, according to a new report.

Leonard Dyck, a botany lecturer at the University of British Columbia, was taking one of his characteristic solo camping trips through the wilderness when he was killed, Robert deWreede, a professor emeritus of botany at the university, told the CBC.

“He was spending a lot of time with his children [lately], sometimes going off on camping trips and so on,” deWreede said. “He often would tell me about the trips that they’d taken together. And I guess one of these trips resulted when he went off on his own camping up north.”

Dyck spent two decades researching botany — with a specific focus on seaweed, according to the report. He earned his bachelor of science in marine biology in 1978, a master’s of science in botany in 1991 and a PhD in botany in 2004, according to the report.

His research — as well as his wife and children — were his favorite topics to discuss, deWreede said.

“He liked to think really deeply about some, what I would consider to be, some rather esoteric biological questions,” the professor told the outlet. “Then, he also was deeply involved with his family.”

Patrick Martone, another botany professor at the university, called Dyck “a really special man” and “truly irreplaceable.”

“He had an amazing depth of knowledge and a way of opening students’ eyes to the diversity of life that we study,” Martone said in a statement issued to the CBC.

“I will miss Len’s laugh, which often followed some wry comment,” he added. “It makes me tear up thinking that I won’t get to hear it again. He held his cards close to his chest, but as soon as you realized how much passion he had for his work, he was so much fun and a joy to be around.”

The university said in a statement that it was “shocked and saddened” to hear of Dyck’s death.

Dyck’s grieving family requested privacy, but issued a brief statement to the CBC.

“We are truly heartbroken by the sudden and tragic loss of Len,” the statement said. “He was a loving husband and father. His death has created unthinkable grief, and we are struggling to understand what has happened.”

Kam McLeod, 19, and Bryer Schmegelsky, 18, have been charged with second-degree murder in connection to Dyck’s death.

Authorities were responding to reports of a blazing pickup truck — which turned out to belong to the teens — last week along Highway 37 when a passing driver told them he spotted what he believed to be a body at a nearby highway pullout.

There, responding cops discovered a corpse — but days passed before they were able to positively identify the body as Dyck’s, according to reports. They released a composite sketch in their bid to firm up his identity.

Authorities believe the teens are also responsible for the slayings of tourist couple Chynna Deese, 24, of Charlotte, North Carolina, and her boyfriend, Lucas Fowler, 23, of Sydney, Australia.

Both teens are likely still holed up in the dense, swampy region around the town of Gillam, investigators suspect — to the horror of local residents.
