Mark Ernsting, 39, died after he was attacked near 38 McGill St., just east of Yonge Street and close to Ryerson University, around 9:30 p.m. ET.
Police say he was stabbed multiple times, including at least once in the head.
“There was no previous relationship between the accused and the deceased,” Det. Paul Worden told CBC News. “The deceased was just out for his normal evening walk and happened to come across the accused and he was attacked.”
CBC News has confirmed that Ernsting worked for the Ontario Institute for Cancer Research.
He was also an adjunct professor at Ryerson University where he worked with graduate students in the electrical and computer engineering department.
About an hour after the attack, police arrested Calvin Michael Nimoh, 21, near Yonge Street and Summerhill Avenue. He is charged with second-degree murder and appeared in court on Wednesday.
Investigators believe Nimoh, who is known to police, may have tried to rob Ernsting.
