DEL RIO - An investigation is underway in Del Rio after Police say four children were hospitalized for "an undetermined illness" that caused them lose consciousness, vomit, and experience dizziness on Halloween.
According to a Del Rio Police Department press release, at about 4:17 PM Wednesday, patrol officers responded to an unresponsive juvenile call at the 700 block of Spring St.
"The call resulted in four children that were hospitalized (at Val Verde Regional Medical Center) for an undetermined illness that caused similar symptoms," the release stated.
The symptoms included loss of consciousness, vomiting, dizziness, and shortness of breath.
Officers later discovered that all four children were handed out candy at a Halloween event in Lamar Elementary School shortly before experiencing the symptoms.
The candy was then tested but nothing was detected, the release said.
The San Felipe Del Rio CISD Police Department took over the investigation as it is believed the incident took place on campus during school hours.
School district officials posted a press release about the incident on the district's website.
The release said all four children were "stable, alert and recovering".
The cause of the illness has yet to be determined.
