Bigelow testified that she began walking away from her sons
to keep Webster’s attention on her. After she was shot and lying on the ground, prosecutors say, Webster shot her 7-year-old son Asa in the back of the head, fired at her 12-year-old son Cooper as he ran to the dental office for help and then firmly pressed his handgun to the back of Vaughn Bigelow Jr.’s head, fatally shooting him. Prosecutors said the impression of the gun could be seen on Vaughn's head.
“It doesn’t get more intentional and deliberate than that,” Chief Deputy District Attorney Jennifer Prince told jurors during the prosecution’s closing arguments.
After the shootings, Webster went to Home Depot to buy a new saw for a home renovation project he was working on for his cousin’s construction company, prosecutors said. A clerk testified that it was a routine transaction. Webster returned to work on the project and was arrested by police after his car, identified with the help of Bigelow’s video, was spotted in rush hour traffic that evening, according to testimony from the home's owner and police.
