April 16, 1910: De Rosier, arrested on charges of corrupting the morals of an underage girl, told The Times that he thought he had treated Pearl well, but assumed she was much older.
In 1911, De Rosier, riding an Indian motorcycle, set several speed records at the Los Angeles Motorcycle Stadium, nicknamed the “pie pan,” but ran out of gas before finishing 100 miles. He was clocked at 41.2 seconds for a mile; 10 minutes, 35 seconds for 15 miles; and 1 hour, 6 minutes, 35 seconds for 92 miles, The Times said. On March 10, 1912, he was thrown against a barricade at nearly 100 mph. He died of his injuries Feb. 25, 1913, in Springfield, Mass., at the age of 33.
