The overdose situation involves four juveniles who swallowed Percocet pills that they thought, but police believe were laced with fentanyl. Around 8 p.m. Tuesday, a father reported his stepdaughter missing, according to the Los Angeles Police Department. He went to Bernstein High School and found her in the yard suffering from a possible overdose. The girl was taken to hospital in stable condition. Before she was taken away, she told her stepfather about another girl in the school bathroom. The man called 911, but when officers arrived they found the other girl unresponsive in the bathroom. He later died. Investigators believe the victims bought the pills in Lexington Park, which is less than a mile from campus. The Los Angeles Fire Department reported two other overdoses at the park earlier in the day. One of those minors was identified only as a 17-year-old. The condition or exact age of the fourth victim was not clear. The LAPD said overdoses are on the rise and they will try to find the drug dealer who sold the pills. There will be an increased police presence in the park on Wednesday. “I think we all share the responsibility in all of our kids. So we all need to talk to our kids, the schools need to talk to our kids. We need to work together to make everyone aware of how dangerous this poison is,” said the lieutenant. John Radtke. In a statement, the Los Angeles Unified School District confirmed that the deceased teenager was a student at the school. The district said school will be open Wednesday and grief counselors will be on site for all students and staff. “As we work together with the LAPD to uncover the details of this tragic situation, our thoughts and prayers go out to the families and friends of both students,” the statement said. Officials say it’s common for drug dealers to lace pills with fentanyl. “This is a scourge and an epidemic that is known across the country. It is unacceptable,” said LAUSD Superintendent Alberto Carvalho. “It’s even more unacceptable when it affects the youth of our community. There is no excuse for this and no tolerance for this.” DEVELOPMENT: We will add more details to this report as they become available. Copyright © 2022 KABC Television, LLC. All rights reserved.
