A Columbus mother accused of killing her 8-year-old son last year changed her plea to guilty on Tuesday. LaShanda Wilder initially pleaded not guilty last July after being charged with murder, abuse of a corpse, endangering children, felonious assault and tampering with evidence in the death of Martonio Wilder. LaShanda agreed to change her plea to guilty on the murder and abuse of a corpse charges. The charges of endangering children, felonious assault and tampering with evidence were dropped. A judge sentenced LaShanda to life in prison with the possibility of parole after 15 years. LaShanda's girlfriend, Johnna Lowe, pleaded guilty and was sentenced to life in prison last month. What happened Officers were called to a home on Olmstead Avenue on reports of a missing child on June 28, 2024. When officers arrived, they spoke to LaShanda, who reported that Martonio was last seen between 9:30 p.m. and 10 p.m. when he was put to bed the night before. Records from the Franklin County Municipal Court show officers searched the home without success, and the Missing Persons Unit responded. Detectives had a K-9 cadaver dog called in to search the home. Court records say, at that time, LaShanda became "uncooperative" and didn't want the dog inside her home. She left the area with Lowe and two other children. Around 6:20 p.m. on June 28, a body matching the description of Martonio was found hidden in the home's attic in a trash bag and sleeping bag cover, according to court records. Firefighters pronounced him dead at 6:33 p.m. and foul play was suspected in his death. Wilder and Lowe left during the active investigation and did not call detectives to explain their disappearance or ask about the investigation, according to court records. They turned themselves in to the police the following day. The Franklin County Coroner’s Office ruled that Martonio died as a result of abuse and malnutrition.
