A Nebraska woman whose son is accused in her murder was likely still alive when the 25-year-old man and his girlfriend dumped her in a southeast Omaha ditch on May 5, a detective said Friday. Roberto Martinez-Marinero stabbed Jesus Ismenia Marinero, beat her with a baseball bat at his home and then, with help from Gabriela Guevara, left the body in a ditch, according to prosecutors. They say he also dumped his 11-month-old half brother, Angel Ramirez-Marinero, in a trash bin and threw his four-year-old half brother, Josue Ramirez-Marinero, from an Elkhorn River bridge. Shocked relatives of Marinero gasped and wept and the judge in the case was prompted to raise the Guevara's bail to $5million in response to Detective Wendi Dye's testimony.Jesus Ismenia Marinero tossed in a ditch in Omaha, Nebraska, on May 5Roberto Martinez-Marinero accused of beating with bat and dumping bodyHad help with ditching body from 25-year-old girlfriend Gabriela GuevaraAccused of dumping 11-month-old Angel Ramirez-Marinero in the trash and tossing four-year-old Josue Ramirez-Marinero from a bridgeInfant found alive with bruises but toddler found dead in water on May 15
