A 12-year-old Nigerian boy has killed his mother, Ayobiyi Cook, at their home in Forestdale, Alabama, United States.

Authorities in the U.S disclosed that the boy initially lied to detectives about what happened. The Jefferson County Sheriff’s Office in Alabama said deputies began investigating the death of a 29-year-old woman in Forestdale, Alabama on Monday.

During the investigation, detectives determined that Cook’s 12-year-old son, who has not been named, unintentionally discharged a firearm, striking and killing his mom.

“The child originally fabricated a story that detectives determined was not possible,” the sheriff’s office said in a news release.

“The child eventually gave a true account of what happened.”

Investigators said evidence supports that the shooting was unintentional.

“The boy’s family, who he will remain with, has been cooperative”, the department said, adding that the case will be addressed through the family court system.

The deceased’s husband, Djuan, in a Facebook post, said Ayobiyi was known as “Yo” or “YoYo.

He wrote, “The funeral arrangements would be held on August 12. Orange was Yo’s favourite colour so feel free to wear it as we celebrate her life.”
