A 24-year-old woman drowned Tuesday night after she and a male friend went swimming in the White River Canal in Broad Ripple. Investigators said the victim, Jessica Adkins, was in the water about 8 p.m. behind the McDonald's on Broad Ripple Avenue when she went under. Witnesses said the victim’s friend, James Petersen, 25, ran inside the McDonald’s and asked them to call 911. He told them he and Adkins were “skinny dipping” when the woman started to struggle in the water. Police said the man showed “indications of being under the influence of narcotics.” He was arrested on several charges, including battery and resisting arrest.
