SPRINGFIELD, Mass. — A Springfield man convicted of fatally stabbing a friend during an argument has been sentenced to life in prison with the possibility of parole in 20 years.

The Republican newspaper (http://bit.ly/2j7hRbf ) reports that Ricardo Valentin was sentenced Wednesday after being found guilty by a Hampden Superior Court jury last Friday of second-degree murder.

Prosecutors say the 25-year-old Valentin stabbed 21-year-old David Guasp in August 2015. The Springfield man died at the hospital.

Valentin was sentenced after Guasp’s mother said in a victim impact statement that her “world stopped” when she learned of the death of her son.

Valentin’s lawyer said the men were friends and that Guasp was the aggressor, but the prosecution said the jury clearly rejected the self-defense argument.
