SAN FRANCISCO—On Friday, June 26, Raymond Wong, 44, was convicted of first-degree murder in the death of girlfriend Alice Sin, 21, back in 1999.

In November 1999, Alice Sin was reported missing by Raymond Wong, when she failed to return home after going out to the store the previous day. Authorities found Sin’s car two days later in the parking lot of a Pinole store.

Two months later, in January 2000, police found Sin’s body in the Nevada Desert. She had been shot four times, once between the eyes, and her body had been mutilated; it was hard to discern whether these mutilations were man-made or by wild animals.

Wong and Sin had shared a son together who, at the time, was barely a year old. It was later found discovered that Sin was also four months pregnant with her second child. He fell under suspicion first when it was discovered that his other girlfriend, Jessica Tang was also pregnant with his child. Police discovered that Wong was listed as Sin’s beneficiary for a $2 million life insurance policy.

Authorities speculated that both Wong and Tang played a role in Sin’s death. She provided Wong with an alibi when he was questioned about his whereabouts when Sin disappeared. Police discovered three days after Sin’s murder, Tang moved in with Wong and they had thrown Sin’s possessions into the trash.

While looking for evidence to convict Wong on Sin’s murder, police found child pornography on Wong’s computer. He was arrested and served 27 months in jail. In 2009, after Wong posted bail he fled to China under a false identity and didn’t return for two years. In 2011, he returned to the United States and was arrested at the San Francisco International Airport.

Wong is expected to face sentencing on September 18, and he is facing 50 years to life. J. Tony Serra, Wong’s attorney, claimed that the jury was bias and he will be seeking an appeal. No details have been unveiled to the public as to rather Tang will face accessory charges because of her health issues.
