'A very, very calm, gentle soul'

Nwonye was just four weeks into the nursing program but he'd already made an impression.

"He stood out," said nursing instructor Rhonda Hersak. "[he was] just pleasant, a very, very calm, gentle soul."

Nwonye was the only man in Hersak's class of 38 students. He was known for getting his classmates talking and stimulating discussions.

News of Nwonye's death "devastated" both Hersak and her students.

She said there is a lot of concern about Nwonye's wife's financial situation. He did not have life insurance and his wife is now caring for their three children, including a three month old baby, alone.

He is scheduled to appear in court on June 23.

The dean of the college's health and wellness program,NoraMacLachlan says counsellors have been brought in to help students cope with Nwonye's death.
