PAWTUCKET, R.I. (WPRI) — The Pawtucket man accused of killing his own grandfather over the weekend will remain behind bars for now.

Matthew Dufresne, 34, has been charged with first-degree domestic murder in connection with the death of 84-year-old Joseph Corsi.

Officers responded to an Eddington Street home for a well-being check Saturday and found an elderly man, identified by family members as Corsi, dead on the floor.

Dufresne, who police said lives with his grandfather, was also home and taken into custody.

Family members described Corsi as “an amazing guy” who loved his Dunkin’.

“He still worked every day and he loved to show people how to cook,” one family member said.

Corsi’s cause of death has not yet been determined.

Dufresne was ordered held without bail and will return to court next week.
