Man pleads guilty to killing former girlfriend

An East Providence man pleaded guilty Wednesday to killing his former girlfriend, who was found dead on Christmas Day 2010.

Prosecutors said Raymond Grundy was sentenced to serve 40 years for second-degree murder under a plea agreement.

Staria Silva found dead in her East Providence apartment on Dec. 25, 2010, by her mother. Silva's 9-month-old twin daughters were found unharmed in their cribs.

The medical examiner said Silva was asphyxiated.
