The Milwaukee County medical examiner is trying to determine if a four-year-old boy died from a drug overdose. Officials say they’re still working to confirm a tentative cause of death for Tyranne Beckless — and it will take a few weeks for toxicology test results to come in. Tyranne was found dead in his north side Milwaukee home last Saturday. At least six other children younger than five have died from drug overdoses in Milwaukee County during the past 19 months.
