Roswell investigators found several of Jeffrey Hazelwood’s writings while searching the homes of his grandparents and girlfriend. But one offered a haunting passage for the 20-year-old, accused of killing two teenagers.

"In one of the writings, he wrote about wanting to be an assassin," Det. Jennifer Bennett testified Friday.

Hazelwood has told police that he became an assassin in the pre-dawn hours of Aug. 1,, though he’s offered no reason.

After spotting Natalie Henderson and Carter Davis, both 17, in the back of her SUV behind a Publix store, Hazelwood told police he watched the teenagers for about 20 minutes. Then, according to Bennett's testimony, he opened the back door of the SUV with one hand while holding a gun with the other.

Within minutes, both Natalie and Carter were dead, according to police. Hazelwood would be at large for 48 hours before police picked him up and charged him with two counts of murder. After his arrest, Hazelwood talked for hours about his actions the night he killed the high school seniors, Bennett said.
