Need help paying expenses for my fathers death

As you may now know my father had been missing for a month. Well we now know much more details and need help. We still owe our private investigator money and unfortunately his life insurance will be tied up for quite some time. I need to get to Oklahoma for at least a week to help take care of his affairs. And it all has become a money pit. Anything can help! Our family is in need and I hate asking for help but I don’t know what else to do! Please help however you can!!
