Two Chicago police officers were struck and killed by passing train while they were responding to shots fired call on the city's South Side.
Eduardo Marmolejo, 37, and Conrad Gary, 31, both fathers of young children, died after they were hit by a train that may have been traveling 70 mph.
the two officers were responding to shots fired call when a suspect made his way up to the Metra tracks.
the suspect was arrested and a weapon was recovered.
the deaths come just one month after Chicago police officer Samuel Jimenez was fatally shot in the neck while trying to protect employees and patients during a shooting at Chicago's Mercy Hospital.
police Superintendent Eddie Johnson told reporters at a news conference at the Police Department's South Side headquarters:
"These brave young men were consumed with identifying a potential threat."
Other police departments, as well as other Chicago police districts, offered their tributes for the latest Chicago officers, members of the department's fifth district, killed in the line of duty.
Passengers were escorted off the train and boarded buses to another stop south to be taken on a new train.
Metra officials shut down all traffic on the Metra Electric District tracks as authorities worked at the scene.
