2 Teens Who Died Of Carbon Monoxide Were 'Beloved' By Teachers, Classmates: Principal

HOFFMAN ESTATES, IL — Two teens died of accidental carbon monoxide poisoning over the weekend, according to Hoffman Estates police.

Emergency personnel responded around 12:30 a.m. Sunday to the 200 block of East Berkley Lane for a report of two people unconscious in a locked vehicle, police said. They found an unresponsive 17-year-old boy and 16-year-old girl, forced entry to the vehicle, and took the teens to St. Alexius Medical Center, where both were pronounced dead, according to police.

“A preliminary autopsy indicates that the cause of death appears to be accidental carbon monoxide poisoning,” police said in a news release.

The Cook County Medical Examiner's Office identified the teens as 17-year-old Yeferson A. Flores Ramos and 16-year-old Litzy Flores.

Both teens attended Conant High School, where Yeferson A. Flores Ramos was a senior and Litzy Flores was a sophomore, according to the school.

In a letter to the school community, Principal Julie Nowak said both teens were "beloved by their teachers and classmates," NBC reported. Nowak went on, "Yeferson was preparing to graduate and had plans to join the U.S. Army. He was a proud Conant student who represented Honduras at our school’s International Fair last week. Litzy was actively exploring her path and was making the most of all of the opportunities at Conant."
