OMAHA, Neb. (AP) — A woman has pleaded no contest to helping her boyfriend dump his mother’s body in southeast Omaha.

Gabriela Guevara pleaded no contest Monday to being an accessory by helping her boyfriend, Roberto Martinez-Marinero, transport and dump his mother’s body in 2015.

Martinez-Marinero pleaded guilty to 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. He was sentenced to life in prison.

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 dumpster. The child was found later, bruised but otherwise uninjured.

He threw the older boy off a bridge to his death.

Guevara will be sentenced in October.
