OSWEGO, N.Y. (AP) _ New York's highest court won't hear the case of a central New York man whose murder conviction for killing his 11-year-old stepsister was reduced by a midlevel court to manslaughter.

Court of Appeals Judge Susan Read has denied requests by 32-year-old Alan Jones challenging his conviction and by prosecutors challenging the reduction. He's serving five to 15 years in prison.  Jones was convicted in 2009 of murder for strangling Erin Maxwell in the family's home in Palermo, Oswego County in August 2008. He was sentenced to 25 years to life.

The midlevel court ruled last year that Jones' murder conviction should be reduced because he wasn't indifferent to whether she lived or died. Authorities had said Jones called 911, performed CPR and waited for medical help.
