An Okotoks man has been sentenced to six years in prison for killing his girlfriend in 2012.

Theresa Enrique was stabbed to death just weeks after arriving in Canada from the Philippines to join her boyfriend Carlos Pelaez.

He had also immigrated from the Philippines to Canada in 2011 to work at a McDonald's restaurant and had secured a position for Enrique.

Her older brother, Ronaldo Enrique, testified she was initially happy with the move but began to feel that Pelaez was very controlling.

"She felt like she was in prison," he said during the trial.

Enrique had packed her things and was in the process of booking a ticket back to Manila when she was killed, her brother testified. 

In his victim impact statement, Ronaldo said he had trouble sleeping and eating after her death.

"It hurt me so much," he said. "She's my one and only sister."

Pelaez was found guilty of manslaughter in February. He was originally on trial for second-degree murder.

He is in Canada as part of the Temporary Foreign Worker program, and faces deportation after his sentence is served.

Pelaez has 35 months left to serve after getting credit for the time he has already spent in the remand centre.
