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

Seattle police say a cryptic phone call helped them save two teenage girls who’d been kidnapped. The department says a 14-year-old called 911 around 1:30 Monday morning, pretending to order pizza, and told dispatch she couldn’t speak freely.

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.
