It’s all in the family. Just one day into the trial, a Los Angeles judge abruptly tossed the suit by Sumner Redstone’s former girlfriend. Manuela Herzer, who was removed as the billionaire’s primary caretaker last year, claimed Redstone, 92, was not competent to control his own estate — or his shares in entertainment giants CBS and Viacom. The court heard slurred videotaped testimony from Redstone calling Herzer nasty names and saying he wanted his daughter to look after him. Herzer’s attorneys contend the testimony was coached and are expected to appeal.
