THREE people were shot dead, including an 11-year-old boy, following a hostage situation Monday in an Oregon home in the United States.

A Marion County Sheriff’s Office deputy was also placed on leave after firing a “yet to be determined number of rounds,” Oregon State Police officials said Tuesday. Authorities have declined to say if any of those dead were shot by the involved deputy.

Deputies responded to a “possible hostage situation” at about 12:30 p.m., officials said, and negotiators called the suspect, identified as Jose Jesus Lopez-Tinoco, 34, of Woodburn, in an attempt to peacefully resolve the situation.

Authorities heard gunshots inside and deputies “forced entry” into the home to try to rescue any victims.

Officials said a deputy who entered the home fired an as-of-yet undetermined number of rounds.

Neighbor Paulina Maciel said her four children and nephew were playing in the backyard when they heard three gunshots. “I was so scared,” Maciel said.(SD-Agencies)
