Girlfriend Pleads Innocent To Killing Man, Flushing Parts

A woman accused of killing her boyfriend and flushing some of his remains into a septic tank pleaded innocent Tuesday to first-degree murder.

Amy Joyce Weir, 33, a waitress and mother of four, entered her plea before Clark County Superior Court Judge James Ladley.

Trial was set for Feb. 17.

Defense lawyer James Dunn told the judge he is studying the possibility of an insanity defense.

Weir is accused of killing and dismembering boyfriend Scott Lee Weisenborn on Oct. 31 or Nov. 1 and flushing at least some of his remains into the septic tank of his home five miles east of Battle Ground, Clark County.

She was arrested Dec. 17 and has been held in Clark County Jail on $750,000 bail.

Sheriff’s detectives, in search warrant documents filed in court, said Weir had talked before of poisoning or blowing up a previous boyfriend.

In their search of Weir’s car, apartment and a storage locker, investigators said they found hair in the wheel well of her car, toilet plungers and books on hypnosis and witchcraft.

Investigators were led to Weisenborn’s septic tank after encountering the strong smell of chlorine bleach - and traces of a human body - in one of the bathrooms at his home.

Weisenborn, 34, was described as quiet and reliable and was a longtime employee of Freightliner Corp. in Portland.
