URBANA, Ill. (WCIA) — The Urbana Police Department and Champaign County Coroner released on Wednesday new information about an Urbana Middle School student who died the previous day, including the student’s name.

Coroner Duane Northrup identified the student as 12-year-old Lucas Cristobal. Northrup and officials with Urbana Police said Cristobal reportedly collapsed in a hallway and was found unresponsive around 12:41 p.m. School staff provided first aid to Cristobal were subsequently joined by emergency personnel from the Urbana Police and Fire Departments. He was taken to Carle Hospital but passed away shortly after arriving at 1:26 p.m.

Northrup said preliminary autopsy results indicated that Cristobal died from a previously undiagnosed medical condition. Final autopsy results are pending toxicology and additional testing.

Urbana Police likewise said there is nothing to indicate that any foul play, malicious or criminal actions had anything to do with the death. They extended their sincere condolences to Cristobal’s friends and family and to school staff members who knew him.

The school, meanwhile, lowered its American flag to half-staff on Wednesday. A school staff member said the gesture was to honor Cristobal and to honor those who died in the attack on Pearl Harbor exactly 81 years prior.

School officials said there would not be a vigil on Wednesday, but they are working on plans for an event during the school day on Thursday. Students were not in school on Wednesday to allow them and staff to process the news and grieve.
