The Sandy man arrested in the shooting death of his younger sister said he shot her "eight times because he thought she didn't deserve to live anymore," according to court documents.

Edward White, 18, was charged with murder, a first-degree felony, in 3rd Circuit Court Monday.Anja J. White, 15, was shot three times in the face and five times in the body with a small-caliber rifle as she lay in her bed last Thursday afternoon, court documents said.

Edward White, 18, was arrested the same day as the prime suspect in the death of his sister and faces life in prison if he's convicted. Prosecutors agreed not to seek the death penalty. White was also denied bail.

Edward White also told officials he was "considering killing his whole family so that he `could get a million dollars life insurance from my dad and live great,' " court documents said.

Police received a call about 1:40 p.m. from a male caller who said a female had been shot and was probably dead. They responded to 854 E. Lafayette St. and coaxed Edward White out of the house. They entered the house and found the body of his younger sister.

Anja White apparently wrote a letter to her father expressing her fears concerning her older brother. Police found the letter, but it was unfinished and her father had never seen it.
