A former Calgary ringette coach convicted of sex-related charges involving a young player on her team has been sentenced to 18 months in jail.

Kelsea Hepburn, 24, began coaching the 13-year-old girl in 2010 and was found guilty of sexual touching and invitation to sexual touching in February.

Hepburn's lawyer had asked that she be allowed to serve her sentence on weekends, but the judge denied that request saying the sentence needs to be a deterrent and not just focus on rehabilitation.

During the trial in February, the teen had described incidents where Hepburn would initiate touching and kissing.

One text from Hepburn to the girl read, "PS you need to be super careful with your phone and erase these messages ... if anyone reads these I'm going to jail."

The court had heard testimony from the girl in which she said Hepburn told her that she frequently felt like a criminal or a predator.

Hepburn coached ringette for six years and will now be putting off university plans to serve her sentence.
