Col. Williams then dragged her bloody, unconscious body up the stairs to her bedroom where he tied Cpl. Comeau to her bed and raped her repeatedly over a period of hours as she struggled.
Cpl. Comeau made one last dash to escape when he left briefly to see if anyone was coming. He tracked her to the bathroom and bashed her in the head again with the flashlight, shattering a picture frame in the struggle. There were at least five blows to her head, face and ear.
He raped her again after the failed escape attempt - this time holding his camera while she pleaded for her life, saying: "I don't want to die. I don't want to die."
Indifferent to her pleas, Col. Williams covered all her airways with duct tape and she suffocated.
When he left the house, he drove to Ottawa for a meeting on the purchase of a C-17 aircraft.
Court was told he took extra precautions to try to cover up how he broke in but made one critical mistake and left a bloody footprint behind that police were later able to match to one of his boots.
The colonel told police he first noticed his second murder victim, Ms. Lloyd, while she was exercising on a treadmill in her basement on Jan. 27, 2010, the day before his attack. But the Crown cast doubt on his story. Ms. Lloyd lived alone on a rural stretch of highway between Belleville and Tweed, where Col. Williams has a cottage.
Col. Williams broke into Ms. Lloyd's home as she slept, restrained her with rope and duct-taped her eyes. He repeatedly sexually assaulted her, videotaping and photgraphing his attacks.
Later, Col. Williams drove Ms. Lloyd to his cottage on Cosy Cove Lane, where he forced her to have a shower while still bound. When she asked for clothes because she was cold, he left her to shiver in the bathtub.
"You have to take me to the hospital. You have to take me to the hospital or I'm going to die," Ms. Lloyd says on video, according to the Crown. She began having convulsions and slurring her words.
Col. Williams ignored her repeated cries for help. She pleaded with him: "I'm not making this up. I'm going to die."
His response? "Hang in there, baby. Hang in there."
Neither Ms. Lloyd's brother Andy nor their mother, Roxanne, who had attended most of the previous hearings for Col. Williams, were in court when the account of her death was read into the record. They left shortly before Cpl. Comeau's murder was described earlier in the day.
Court was also told that shortly after 9 a.m. on the day after the attack began, Ms. Lloyd's mother received a call from her daughter's employer, a school-bus company, saying that she had not reported for work.
The family later phoned the police, who discovered tire tracks in the field near her home. After publicity surrounding Ms. Lloyd's disappearance, three witnesses who had noticed an SUV parked nearby contacted the police. Col. Williams drove a Pathfinder SUV.
For several hours that same afternoon, Col. Williams forced Ms. Lloyd to model lingerie, duct tape still covering her eyes. Later, he gave her fruit and suggested they would leave. As she began walking, he struck her on the head with a flashlight, knocking her out and causing her to bleed. Then he strangled her with a rope and put her body in his garage.
Col. Williams spent that night at CFB Trenton and flew troops to California the next day. When he returned home three days later, he dumped Ms. Lloyd's body in an isolated area off a rural road.
After the Ontario Provincial Police narrowed the tire tracks in the field to tires used only on SUVs, officers set up a roadside canvas. In a stroke of luck, Col. Williams drove up in his Pathfinder within minutes. His tires were a match. Police set up surveillance and followed him to an Ottawa car wash, where he vacuumed out his vehicle. After he left, officers seized the vacuumed materials.
Police obtained a search warrant for his home, but first invited Col. Wililams for a voluntary interview. He attended and answered questions, despite a reminder that he had the right to contact a lawyer. He gave a print of his boots, which matched a print found in the field behind Ms. Lloyd's house.
