The Snapchat Video of Alec's Killing

Housekeeper Blanca confirmed that the clothing Alec was wearing in the Snapchat video was not the same clothing he wore when he left for work. She knew this because she helped him fix his collar that morning, and she got a good look at what he was wearing. This would suggest that he changed two times after coming home from work. And like the prosecution alleges, Alec could have changed a second time so that he could get rid of the clothes he was wearing when killing his wife and son.
