TACOMA, Wash. -

A 69-year-old Puyallup, Wash., man has been sentenced to five years in prison after pleading guilty to two counts of second-degree murder in the 2013 shooting deaths of his adult daughter and son in his home.

Family and friends asked for leniency for Michael League.

Defense lawyer Mary K. High told Superior Court Judge Garold Johnson on Thursday that the victims had turned League's life into a nightmare by stealing from him and his wife and verbally and physically abusing them.

The judge said League must serve some prison time for taking two lives but he did acknowledge a pattern of emotional and physical abuse.

Dennis League and Danielle Faucett were shot as they slept.

League told the judge he still loves his children and will always regret what he did. When he called 911 to report the shooting, he called it "a father's worst sin."
