Canada police say who killed 9-year-old girl 36 years ago.

TORONTO (AP) — Canadian police announced Thursday that they have identified the person who killed a 9-year-old girl 36 years ago — a slaying for which another man was wrongly convicted.

Toronto Police said that Calvin Hoover was identified through DNA. He died in 2015. He was 28 years old at the time of the murder and knew the family of Christine Jessop, though he was not a suspect at the time.

Jessop was last seen on Oct. 3, 1984, in Queensville, Ontario, north of Toronto. Her body was found over three months later. She had been sexually assaulted and stabbed to death. Police found DNA evidence on her underwear.

Her case received national attention and her neighbor was wrongly convicted. Guy Paul Morin was sentenced to life, but his conviction was overturned in 1995 based on DNA technology. He was paid more than a $1 million and received a public apology.
