A woman grieves during funeral services for the late Spanish Rev. Mariano Arroyo Merino in Havana, 17 Jul 2009Mourners gathered in Cuba's National Cathedral Friday to honor the second Spanish priest killed on the island in five months.

Authorities said the Reverend Mariano Arroyo Merino was found dead Monday at his parish building in the Havana Bay area and that a suspect has been arrested. Cuban police said the suspect has confessed to murdering the priest.
 
Authorities have not released any more information about the suspect or a possible motive for the murder.

Church officials said Arroyo's slaying is not related to the case of Eduardo de la Fuente Serrano, another Spanish priest found dead outside Havana in February.  

Authorities planned to fly Arroyo's remains to Spain for another service in his honor following the funeral in Havana.
