People.com Crime Grandmother Said Idaho Girl, 8, Had Run Away, But Then Child's Body Was Found in Her Car: Police In a probable cause affidavit, police have revealed details about the case of slain 8-year-old Taryn Summers By Steve Helling Published on April 20, 2021 10:36 AM Share Tweet Pin Email Photo: Gofundme; Ada County Sheriff’s Office The body of a missing Idaho 8-year-old was discovered last week inside a garbage bag in the backseat of her grandmother's car — and authorities have filed charges against the grandmother. According to court documents obtained by KTVB-TV, 54-year-old Connie Ann Smith of Emmett, Idaho, called police on April 12 to report that her granddaughter, Taryn Summers, had run away. When police arrived at Smith's home, they noticed that part of the carpet in the girl's bedroom was missing. Smith allegedly told them that she had removed part of the carpet and burned it because the girl had defecated on it. After a search of the surrounding area, forensic crews returned to the home on April 14. They allegedly found a spot of blood on Taryn's wall. According to the probable cause affidavit, authorities then discovered Taryn's body in a black plastic garbage bag on the floor of the back seat of a black Lexus. Investigators said that the little girl was covered with vomit. Smith was initially charged with first-degree murder, but is now instead charged with felony failure to notify a death and felony destruction, alteration, or concealment of evidence. Police say that more charges are forthcoming. Want to keep up with the latest crime coverage?
