Elderly father attacked and robbed

On the morning of September 4th, my father, Albert (age: 80) traveled to Kingwood, TX to pick up myself and my wife.  He took a wrong turn and pulled in a gas station to ask for directions.  While receiving the directions he noticed a man breaking into his car. He went outside to confront the man and stop the robbery. The man then grabbed my dad's keys from him, hit him and knocked him unconscious. As the man began attacking him, my dad fell,  smashed his face into the concrete and busted his face open. His head was also busted open and both eyes bruised. His right shoulder was dislocated. The man then got back into my father's car and made an erratic u-turn nearly running my dad over. The police officers said he would have died had it not been for a good samaritan dragging him out of the way. The man drove less than a mile before he totaled out my father's car. It's been 10 days now and my father is still hurt, still bruised and unable to use his right arm without pain. He is the sole caregiver for his wife whom has fading health and needs a lot of attention. They need a car,  help with a nurse, ramp for walker, physical therapy, ect. My father is proud and won't let this wreck his spirit, but truly needs help!
