A New York jail guard has pleaded guilty to murder and other charges for killing her ex-girlfriend and uncle, and wounding her grandfather.

Kim Wolfe entered the plea Wednesday to two counts of murder, one count of kidnapping, assault and a weapons charge. The judge said he will sentence her to 22 years to life on Nov. 2.

Stacie Williams, a 45-year-old nurse's aide, was gunned down last year outside the Nassau University Medical Center in East Meadow on Long Island. The pair had met to discuss a possible reconciliation.

Wolfe then went to a relative's home about three miles away in Hempstead. There, she killed her uncle, wounded her 88-year-old grandfather and took a 23-year-old niece hostage following a dispute over life insurance policies. The niece was not harmed.
