A Colorado Springs woman charged in the brutal slaying of her mother-in-law appears headed for trial.

Ellyzabeth Rainey was scheduled for a March 10 jury trial on Tuesday after entering not-guilty pleas before 4th Judicial District Judge Barbara L. Hughes.

Rainey, 20, is charged with first-degree murder and other counts in the April 3 death of Deborah Rainey, who was beaten, stabbed and doused with boiling water and bleach in the defendant's Colorado Springs apartment.

The victim, who lived in San Francisco, was visiting her son and daughter-in-law to help care for their newborn, police said.

Rainey, who told police detectives she had been hearing "voices" before the attack, is scheduled to return to court Jan. 17 for pre-trial motions.
