Andrea was barely alive when Caleb drove her to a wooded area and dumped her body.
He returned later that evening after putting their two children, aged 4 and 11 months at the time, to bed.
Caleb attached a backpack to Andrea filled with weights and chunks of rock, drove to a nearby bridge, and dumped her body into the Occoquan River.
The next day he called police and reported Andrea missing, claiming she had disappeared after an argument.
Andrea’s body was discovered by a fisherman days later.
Caleb eventually confessed to Andrea’s murder.
“I took the phone. I grabbed her out of her chair. She only weighs 8 stone. I grabbed her throat and strangled her in the back seat,” Mirror reports Caleb said. “First thing I said was ‘Goodbye’.
I knew once I went down that path I couldn’t go back. She said, ‘Please Caleb’, I started crying but I couldn’t stop.”
When asked why he’d used his tie after strangling her, he replied, “To finish the job.”
Lingan referred to Caleb’s actions as “pure evil.”
