A Nigerian Catholic priest, Rev. Benjamin Madu who had been preparing to leave the United States after his religious worker visa expired has died in Massachusetts, church officials have confirmed.

Madu, a priest of the Diocese of Abakaliki in Ebonyi State, died on Thursday after serving for several years as a hospital chaplain and parish priest in Massachusetts.

In announcing his death, Father Jim Achadinha, pastor of the Catholic communities of Gloucester and Rockport, described it as a “devastating loss.”

Achadinha said Madu “served Holy Family Parish and Our Lady of Good Voyage Parish with true joy, kindness, and generosity.”

Authorities have not disclosed the cause of death.
