A Taunton man was sentenced to life in prison today for the 2009 murder of his girlfriend, a Waltham resident.

A Middlesex Superior Court jury yesterday convicted Souleymane Yacouba-Issa, 37, of murdering Maryse Antoine, 46, of Waltham.

Yacouba-Issa is not eligible for parole, according to the Middlesex County District Attorney’s Office. Yacouba-Issa is already serving a 3-4 year prison term for stalking Antoine, of which he was convicted last November.

Yacouba-Issa was previously tried on the murder charge in November, but that the jury was hung on that charge, according to the DA’s office.
