A High River man who assaulted three boys while in Calgary as a Baptist Church volunteer will be sentenced on Friday.

Russell Rodman, 59, pleaded guilty in November 2012 to sexual assault, gross indecency and sexual contact.

His victims were between the ages of 11 to 14 and the attacks happened between 1981 and 1995.

The Crown asked Monday that Rodman be handed a sentence of three and a half years in jail.

The defence wants him to serve 18 months.
