ALLENTOWN — The late IndyCar driver Justin Wilson saved six lives Tuesday by donating his organs, his brother said. “He just keeps setting the bar higher,” Stefan Wilson posted on his Twitter page. “Keep Julia & the girls in your prayers #myherojw.” The 37-year-old Wilson died Monday night from a head injury suffered when a piece of debris struck him during a race the previous day at Pocono Raceway. A British driver who lived in Colorado, Wilson was hit in the head by piece of debris from another car. Wilson drove a Honda from 2008 through 2015 in IndyCar, and the manufacturer offered its condolences Monday. — Reuters
