13-year-old Megan Swanson from Seattle was videotaping the Holiday Festival of Lights Parade off Harbor Island on Dec. 20, 2009.The video shows a Coast Guard boat with flashing lights speeding across the water. A mans voice is heard in the background saying, Why are these guys going 20 knots? It just doesn't make any sense.Then, a loud crash was heard. The collision that killed 8-year-old Anthony DeWeese was not shown on the video, but the video does show the Coast Guard boat calling for help and records a chilling cry from Anthony's mother as she called out her son's name.The DeWeese family attorney played the home video during the court martial of the man driving that Coast Guard boat, U.S. Coast Guard Petty Officer Paul Ramos. Ramos said he was responding to a stranded yacht. He is facing negligent homicide and involuntary manslaughter charges."It was a disaster on that boat," said Mike Neil, the attorney for the DeWeese family. "There was chaos on that boat. They were totally taken by surprise when all of a sudden when they were over-run by this Coast Guard boat."The owner of the yacht the Coast Guard was racing to assist has said he was not in danger and that his call for help was not urgent.
