Three people died and one was seriously under injured during a “hostage situation” in Salem, Oregon, Monday, police said according to the Associated Press.

Deputies from the Marion County Sheriff’s Office responded to a call of a possible hostage situation at around 12:30 p.m. Monday, according to a police press release. Deputies began communication with Jose Jesus Lopez-Tinoco in an effort to resolve the situation, the police reported according to the AP.

Deputies arrived at the home and called a trained negotiator, who was on scene and attempted to speak with the suspect over the phone, but “shots were fired,” CNN  reported. Deputy Ricky Kittelson fired a yet to be determined number of gunshots, state police said according to the AP, but police did not say if Kittelson hit anyone with gunfire.

“There were multiple fatalities during this incident, including that of the suspect,” the initial release said. (RELATED: Minneapolis Police Department Investigating Project Veritas Claims Of Voter Fraud)

The police said Lopez-Tinoco was found dead by what appeared to be a self-inflicted gunshot wound. Diari Bustos-Bustos, 24, and an 11-year-old boy were found dead with gunshot wounds, according to the AP. Laura Rocio-Bustos, 43, was taken to the hospital with injuries fro a gunshot wound. Another boy, 13, was rescued from inside the residence and was uninjured.

No deputies were hurt, the sheriff’s office said.

The Oregon State Police were called to the scene to investigate the officer involved shooting, per the sheriff’s office policy and county protocol. Kittelson, who has worked for the sheriff’s office for two years, was placed on administrative leave while the incident is investigated.
