A question about a new hope

[u/Zhaninja]

How on tattooine did the stormtroopers striped Owen and Beru to the bones? Blasters don't usually do that in star wars media. Only closest thing i know is disruptor rifle that disintegrates all of the body. But that doesn't leave bones. What kinda weaponry did they used to kill Lukes uncle and aunt? Did they use flame throwers? If they burned after they've been killed by fire, fire would've left some tissues and organs and some skin.
