On the afternoon of the attack, McBride and Myers decided to take a walk in the
Braemar Hill countryside, part of the
Tai Tam Country Park, located near McBride's residence at
Braemar Hill Mansions. They were seated on a remote and quiet pathway on the hillside, studying for their
A Level examinations. Earlier the same day, a group of five local
triad members: Pang Shun-yee () age 24, Tam Sze-foon () age 20, Chiu Wai-man () age 25, Cheung Yau-hang () age 17, and Won Sam-lung () age 16, were gathered in the area. According to Won's evidence, Pang was the leader of the group, and he suggested they steal a cable from the government aerial station on the mountain for some extra cash. After several failed attempts to steal the cable, the group spotted McBride and Myers. The group decided to "have some fun" and thought as the teenagers were European they must be rich. Pang led them to
rob the couple. McBride and Myers only had one dollar on them, angering the gangsters and triggering the attack. McBride was bound and savagely beaten. Tam pulled off McBride's
Nike shoes and kept them after the murder, leading to the shoes becoming key pieces of evidence presented in court. According to the murderers' statements, Pang verbally threatened the rest of the gang to take part in the attack. Pang
raped Myers while the other four members were brutally beating McBride. Myers' genitalia were penetrated by a stick and a bottle. After several attacks, Pang decided to murder the couple to prevent later identification. The group left the country park after the murders, and destroyed the couple's textbooks. ==Investigation==
