Detectives named Nelson Fermin Garibay as the suspect wanted in connection with the deadly attack that took place Monday in the 14400 block of Marwood Street and also injured his 37-year-old brother, according to the Los Angeles County Sheriff's Department.
Deputies who responded to an assault with a deadly weapon call at the home were met outside by a man who said he had been attacked by Garibay, the department said.
The injured man led deputies inside the home where the two other victims were found. Each had sustained significant head trauma and were pronounced dead at the scene. The injured victim was taken to a hospital with non-life-threatening injuries, according to the department.
