The two officers responded Monday to a shots-fired call – issued after a ShotSpotter sensor detected gunfire – and followed Brown, who ran onto the train tracks, Chicago police said.

The two officers responded Monday to a shots-fired call – issued after a ShotSpotter sensor detected gunfire on the city’s South Side – and followed Brown, who ran onto the train tracks, Chicago police said. A passing metro train struck and killed the officers, authorities said.

Brown was taken into custody that day after he was seen firing a gun in the area, Chicago police said.

Body camera audio indicates that officers Conrad Gary and Eduardo Marmolejo were aware of a northbound train in the area during the chase, but they did not realize a southbound train was approaching, according to police Superintendent Eddie Johnson.

The noise from the northbound train apparently masked the sound coming from the other train, said police spokesman Anthony Guglielmi. There’s no indication the officers saw the southbound train before it struck them, he said. It was traveling at 60 to 70 mph.

The two died instantly, police said.

Gary, 31, had been on the force 18 months. Marmolejo, 37, joined the department 2½ years ago, Johnson said.

Gary’s wake is scheduled to be held on Thursday and his funeral on Friday, police said. Marmolejo’s wake is set for Friday and his funeral will be Saturday, police said.

Brown has no criminal background and works as a prep chef at a restaurant downtown, according to information gleaned during Thursday’s court proceedings.
