Only two things have officially been released by LE concerning physical description - the perp's gait with right foot turnout, and his height. Height was originally estimated to be 6' - at least BB was saying that's what LE were saying. In an earlier thread, when a later article posted said that LE now listed 5'9" as the tallest estimate I was turning cartwheels, as I thought the same as you--this was not a tall person. I'd been using Texas building codes (door handle heights) and had gotten anywhere from 5'3" to 5'9" - but never 6 feet tall. (Hubby is in TX construction and identified the door I was measuring suspect against as a 70" tall interior door, with handles generally 36" up from the bottom.) This is why I can't for the life of me understand all the ppl who are adamantly pointing fingers at at Missy's husband, who is at least 6' tall and probably taller.
I'll see if I can round up the link for you.
ETA: this is not to say I haven't found some media interviews to be odd (though that could be for several reasons, including numbness and shock)...just that I don't think BB could have been the person in the SWAT gear. Can't shorten your height for disguise purposes.
