KANSAS CITY, Mo. (AP) — A Missouri woman who tried to have her former son-in-law killed so she could see her grandchildren more has been sentenced to four years in federal prison.

Sixty-three-year-old Teresa Owen of the Kansas City suburb of Independence was sentenced Thursday. She pleaded guilty last September to using a telephone to commit a murder-for-hire scheme.

Authorities say Owen was embroiled in a custody dispute involving her grandchildren when she reached out to two people by telephone, offering them money to kill her former son-in-law. One of the would-be hit men turned out to be an undercover police officer.

Investigators say Owen agreed to pay $700 for the killing said she wanted her former son-in-law’s death to resemble an accident.

She was arrested and charged in mid-2015.
