Boy, 12, Held in Slayings of Grandmom, Aunt

MARIETTA, Ohio – A 12-year-old boy was being held Tuesday in the shotgun slayings of his grandmother and aunt at a rural home, deputies said.

Nancy Tidd (search), 61, and Emma Tidd (search), 40, each were shot in the head with a shotgun Monday, the Washington County sheriff's office said.

Washington County Prosecutor Michael Spahr said he would charge Christopher Sturm with juvenile counts of delinquency by murder and delinquency by aggravated murder. A 12-year-old cannot be tried as an adult in Ohio.

Deputies said Sturm, who was in juvenile detention, told relatives he shot the women.

"From the information we have, the boy was upset at the grandmother, and that led to the shooting," detective Jeff Seevers said.

Investigators said Sturm divided his time living with his mother and grandmother. He was found at his mother's home about six miles away in Lower Salem (search), 90 miles southeast of Columbus.

The grandmother was unable to defend herself because of a medical condition, and there was no sign of a struggle, Seevers said.

The bodies were discovered by a relative who went to the house to check on the two women.
