'Key detail': Expert flags 'significant development' in manhunt for Minnesota assassin

There is a "key detail" to be considered in the Minnesota manhunt for the man who allegedly killed a Democratic lawmaker and her husband, and injured another lawmaker and his wife.

CNN's chief law enforcement and intelligence analyst, John Miller, appeared on the network on Saturday to talk about the shooting of four Democratic-linked individuals in Minnesota. Donald Trump's own niece has tied the president to the unfortunately political assassinations.

Miller, on the other hand, highlighted how different the alleged killer, Vance L. Boelter, looks in various pictures being displayed in the media.

"Take a look at this poster. This is the FBI's wanted poster for Vance Luther Boelter. The picture on the far left. That is his driver's license photo from the state of Minneapolis. The picture next to that is from the website of his security company. The next picture shows him with a shaved head. Now that, according to law enforcement sources in Minnesota, is taken this morning during the actual crime where he's wearing that tactical bulletproof vest, he's got a flashlight and he is trying to gain entrance or leave one of the houses where these shootings actually occurred. So that is key because it makes a difference if he doesn't appear like the two pictures on the left, because he has shaved his hair or lost his hair, that is a significant development. Now that picture to the right, there he is in the cowboy hat, spotted at a business this morning in Minneapolis. So that would be the last known photo. But because of the cowboy hat, you can't tell exactly what he looks like there, underneath the hat."

Later in the appearance, Miller suggested the bald look was due to a "mask."
