Bow Kum (1888 – August 15, 1909) known as Sweet Flower was a Chinese-born slave girl who belonged to the Hip Sing Tong and later to the On Leong Tong around the turn of the 20th century. Her murder was one of the most well-publicized and notorious crimes in New York's history and was the cause of the year-long Tong War between the On Leong Tong and its rivals the Hip Sings and the Four Brothers.
