Expert: Murder suspect wrote incriminating notes

A handwriting expert says a teenager charged with murder in a New Hampshire home invasion last year wrote detailed summaries of the attacks.

Document analyst Alan Robillard testified Thursday that 18-year-old defendant Steven Spader wrote the letters Spader termed "bedtime stories" to another inmate.

Song lyrics also said to be in Spader's handwriting include the lines: "We went up in the room, Mommy is it you?, Mommy isn't here, I slit her throat from ear to ear."

Prosecutors say Spader wielded a machete in the attacks that killed Kimberly Cates and maimed her 11-year-old daughter, Jaimie, in their Mont Vernon home.

Spader has pleaded not guilty to first-degree murder, attempted murder and other felonies.
