Omaha Man Admits Killing Mother, Throwing Brothers In River And Dumpster: Police

Police in Nebraska are searching for a missing 5-year-old boy after they said his brother confessed to throwing him in a river after killing their mother.

Roberto Martinez-Marinero, 25, turned himself in to Omaha police on Thursday night, a day after the body of his mother, 45-year-old Jesus Ismenia Marinero, was found in a ditch. Investigators said he confessed to killing his mother, and to putting his 11-month-old brother in a nearby dumpster. The baby was recovered unharmed and reunited with family members.

The suspect's 5-year-old brother, Josue Ramirez-Marinero, is still missing. Police said Martinez-Marinero admitted throwing the boy into the Elkhorn River. The Omaha Police Department is conducting a ground, air and water search along the river, with help from the FBI and other law enforcement agencies, according to
