A young Omaha man accused of killing his mother and his four-year-old half-brother has pleaded guilty to avoid the death penalty.
25-year-old Roberto Martinez-Marinero pleaded guilty to two counts of first-degree murder.
Martinez-Marinero eventually turned himself in to authorities in Douglas County, confessing to detectives that he had killed his mother, 45-year-old Jesus Ismenia Marinero, and his brother, Josue Ramirez-Marinero. Martinez-Marinero also confessed to discarding his 11-month-old Angel Ramirez-Marienero in a dumpster. Angel has been returned to his father, Jose Ramirez.
Martinez-Marinero says he killed his mother in a dispute over money. He says he threw Josue off the West Center Road Bridge into the Elkhorn River. The boy’s body was recovered May 11th.
Douglas County Attorney Don Kleine dropped his pursuit of the death penalty after Douglas County District Judge Marlon Polk sentenced Martinez-Marinero to life in prison.
