OMAHA, Neb. (AP) — A woman has been sent to prison for helping her boyfriend dump his mother’s body.

25-year-old Gabriela Guevara was sentenced Friday to six to 14 years in prison. She pleaded no contest in August to being an accessory.

Guevara’s one-time boyfriend, Roberto Martinez-Marinero, is serving a life sentence for two counts of first-degree murder in the deaths of his mother, 45-year-old Jesus Ismenia Marinero, and his 4-year-old half brother, Josue Ramirez-Marinero.

After killing his mother, Martinez-Marinero took her two youngest children in an attempt to eliminate witnesses. He dumped his then-11-month-old half brother in a La Vista trash bin. The child was found later, bruised but otherwise uninjured.

He threw the 4-year-old boy off a bridge to his death.
