Jerry Sichting, a Martinsville native who played for Purdue and the Indiana Pacers, will serve as the interim head boys basketball coach in his hometown after the former coach was arrested on a public indecency charge.Tim Wolf, 65, of Martinsville, was found "in a state of nudity" in his car at Eagle Creek Park about 3:50 p.m. Sunday with a 17-year-old girl, also from Martinsville, in the passenger seat, police said.Martinsville school officials said Sichting reached out to them after the news broke and asked how he could help the team.It's difficult. I know Tim Wolf. I've known him for a number of years. It's just a difficult situation," Sichting said. "His son, T.J., is going to be on staff. I'm going to rely on him quite a bit because I don't even know the plays."Sichting, a 1976 graduate of Martinsville High School and former NBA player and coach, will take over coaching duties for the remainder of the season and the postseason, but he doesn't plan to return next year.Sichting played at Purdue University from 1976 to 1979, where he was co-captain of the 1979 team that shared the Big Ten championship.He won an NBA championship with the 1986 Boston Celtics, highlighting a 10-year career with Indiana, Portland, New Jersey, Milwaukee and Boston.Sichting was on Celtics radio broadcasts for four years and coached for 14 years. He was also an assistant coach in the NBA for 13 years and is a 2002 inductee into the Indiana Basketball Hall of Fame.The Martinsville boys team plays Friday at Whiteland and at home Saturday against Irvington Prep Academy. If they win Friday, they'll win the Mid-State Conference title outright for the second-straight year. If they lose, they will share the title with Mooresville.Martinsville Schools Superintendent Ron Furniss said Wolf would retire, effective immediately, pending school board approval. The school has also launched an internal investigation."We heard the rumors, just like everyone else heard the rumors, and when we tried to chase them down, we couldn't find any substantiation," Furniss said. "If you're going to accuse somebody, you better have some proof."Kenny Costin, president of the school board, said the Wolf situation has been hard to deal with."You have disbelief, and then you realize that we have to make a decision that isn't an easy one," Costin said. "Coach Wolf was a friend of mine, and I've known him for several years. It's just hard to step back and think, 'What are we going to do that's fair for the school district and also fair for him?'"Wolf had been a teacher and coach at Martinsville High School for 25 years. The school board is scheduled to meet with an attorney Thursday to discuss options."I personally don't think we'll make a decision until sometime next week, because this is something that is going to affect our school system and also going to affect Mr. Wolf and his family," Costin said. "There's going to be some legal ramifications. We want to make sure we do the right things."
