RENO, Nev. (AP) — A 66-year-old Reno man who police say was driving an SUV that plowed through a house where two children died has had his driver’s license suspended six times since 2002, but none of the suspensions stemmed from criminal convictions, state records obtained Wednesday show.Reno police were investigating whether Sheldon Berg had a medical event before his Subaru crashed into the home on Monday. A 2-year-old boy and 4-year-old girl were killed.The names of the children who lived in the modest neighborhood near downtown have not been released.No charges have been filed, and police said they do not believe drugs or alcohol were involved.Berg has an active, restricted license issued in March that doesn’t expire until April 2019, although it requires an annual doctor’s note.He has been required to submit letters from a doctor certifying his ability to drive at least since 2013, when he was involved in an accident after suffering a medical episode, according to the Nevada Department of Motor Vehicles. Police said Berg struck two unoccupied vehicles and was the only one injured.His license was taken away on March 6, 2013, and suspended about 12 weeks before being reinstated.
