Help with Luke’s medical bills!

Luke (my brother) was hit by a truck in gulf shores Alabama Friday night 7/4. He was left with a broken pelvis and was due to ship out to the army Monday and now he’s stuck with an enormous medical bill and the person that hit him fled the scene. He doesn’t have health insurance because he was joining the army the first of the week. Anything will help because now he will have to have a new plan because the army will not accept him with these injuries. Thank you.
