An Ottawa man has died after an altercation inside the Collins Bay Institution in Kingston, Ont.

Shawn McKenzie, 24, died late Monday from injuries suffered in a fight Sunday with a 41-year-old prisoner.

The 41-year-old was taken to hospital but later returned to the federal institution. Ontario Provincial Police are now investigating and an autopsy has been scheduled.

McKenzie was first sentenced to life in prison with no chance of parole for 10 years after killing a man over his iPod in 2006.

McKenzie convicted of killing man over iPod

The victim, 23-year-old Michael Oatway, was stabbed in the back of an OC Transpo bus in September 2006 after four young males approached him.

McKenzie, the court was told in 2009, demanded Oatway's iPod and when Oatway refused to give it to him, McKenzie stabbed him in the chest.

The judge decided to sentence McKenzie as an adult, thus allowing his name to be released.

He would have been eligible for parole in three years.

The Collins Bay Institution can hold almost 500 prisoners but it is currently being expanded to include a 96-bed living unit, which could be completed this year or in 2014.
