A man shot and killed his pregnant wife and their two children before he killed himself, according to authorities.

Four family members who were found dead in a Rhode Island home last week were the victims of a triple murder-suicide, law enforcement officials announced Wednesday.

According to West Greenwich police, Nicholas Arruda, 39, shot and killed Danielle Arruda, 39, Adele Arruda, 5, and Felix Arruda, 2, before turning the gun on himself. Danielle Arruda was seven months pregnant at the time of her death.

Police say Nicholas D. Arruda, 39, shot and killed his pregnant wife, Danielle, 39, and their two young children. “My brother committed the most cowardly despicable act one could perpetrate,” Arruda’s brother said.

Police continue to investigate after a family was found dead in their West Greenwich home last week. President Biden stood next to Gov. Gavin Newsom and pledged full federal support as fires burned through Los Angeles County.
