Authorities said suspects were in custody in connection with the shooting death of an off-duty Cook County Sheriff's investigator outside of a holiday party Friday night in a Chicago suburb.
The Cook County Sheriff's Office confirmed Sunday that multiple suspects were in custody, but could not offer any further details. Charges were dependent on the Cook County State's Attorney, officials said.
Officer Cuauhtemoc Estrada, 50, was fatally shot outside of a family Christmas party at the VFW Bellwood Memorial Post 5081, on the 200 block of 30th Avenue, in west suburban Bellwood while trying to stop the armed robbery of his daughter's boyfriend.
Family members said Estrada confronted two masked men with a large gun who were robbing his daughter's boyfriend outside of the party.
Shots were fired around 7:30 p.m. when Estrada tried to intervene in the attempted robbery, officials said at a news conference.
Estrada was shot in the chest while reaching for his weapon, according to Bellwood's Public Safety Director Andre Harvey. It was not clear whether Estrada was carrying a service weapon or a personal one.
Cook County Sheriff Tom Dart said Estrada was a former U.S. Marine and a 20-year veteran of the department. He worked in the department's electronic monitoring unit, according to sheriff's spokesman Ben Breit.
"It's horribly sad for everybody," Dart said. "He was an amazing person."
