Gruesome details emerged on Tuesday as the High Court heard the case of a security guard accused of murdering his girlfriend with an electric drill at a construction site in Tuen Mun. The defendant, Safdar Husnain, who was 27 when the incident took place in the early hours of March 29, 2016, had earlier pleaded not guilty. The deceased, 25-year-old Andrea Bayr, was found to have a hole in the right side of her face, among other injuries, with part of a drill bit protruding from the wound. Traces of crystal methamphetamine, also known as Ice, were found at the scene and in the victim’s blood and urine.

Inside the unlit area, officers found a green container, which served as an office, with the door open. Witness Tin Yun-lam, one of the patrol officers called to the scene, told seven jurors that he and his colleagues saw nobody inside the office, but noticed a bloodstained plastic bag on the ground. Tin said when officers continued their search, they heard a noise nearby. When they investigated the noise, they found Husnain and Bayr sitting on the ramp of a footbridge, with Husnain, shirtless and barefoot, facing forwards, holding a black electric drill and wrapping Bayr’s waist with his legs. Bayr’s head was face up, resting on Husnain’s stomach. “The man lifted the electric drill, moved it down and attacked the woman’s head,” Tin said. “The woman made no response to the attack.” Tin said officers immediately subdued Husnain, who kept shaking his head and repeating “sorry” in English with his eyes closed.

Prosecutor Terence Wai Hon-hei said an autopsy revealed multiple injuries all over her body with significant ones to her head and neck. Besides the wound from the drill, she had also suffered multiple blunt force trauma to the head. Deep bruises were found in her neck muscles and the cartilage near her voice box was fractured. It was believed that she also suffered substantial pressure on her neck. A forensic expert believed either head or neck injuries, or both combined, were sufficient to cause Bayr’s death. Officers found three plastic bags containing 0.82 grams of Ice in the office. Bayr’s blood, stomach and urine were also tested and were found to contain traces of the drug. Witness Lam Tze-tsun, a chemist at the government laboratory who was called to examine the scene, said Bayr’s blood was found all over the office, and a pool of her blood was found on the ramp where she and Husnain were found, leading him to believe that she could have been first attacked in the office, ran outside and eventually collapsed on the ramp.
