Anthony Ler Wee Teang (c. 1967 – 13 December 2002) was a Singaporean convicted murderer who hired a youth to murder his wife, 30-year-old real-estate agent Annie Leong Wai Mun, who was in the midst of a divorce with him. Ler's motive was to become the sole owner of their flat and to gain custody of their four-year-old daughter. Ler approached five youths and offered them a reward of S$100,000 to kill Leong. A 15-year-old boy whom Ler had known for five years accepted the offer. Ler threatened and manipulated the youth to carry out the deed. After several failed attempts, the youth fatally stabbed Leong.
