A man who killed his neighbor after she found him burglarizing her home outside New York City is heading to prison.

Authorities say 33-year-old Lloyd Lewis was sentenced Thursday to 22 years to life in prison. Lewis pleaded guilty in March to killing 85-year-old Emma Gruber.

Investigators say Lewis broke into Gruber's Mount Vernon home in February 2014 to steal copper pipes. They say he bludgeoned her to death with a piece of plywood when she interrupted him.

She was discovered two days later under a pile of clothes at the bottom of her basement stairs. Authorities say Lewis sold several items from Gruber's home to a pawn shop and scrap yard.

Gruber was well known in her neighborhood and at Greater Centennial AME Zion Church, where she was an usher.
