Vladimir, is this your sister?!?!
Yes. Pray for her immortal soul, since I do not know if she has made her peace with God or not. I have been praying to St. Joseph the past days, first for her safety, but now I think that it is best to pray for the welfare of her soul. As far as I could tell, she was not a practising Catholic, and I hope that if she still draws breath that she will turn to God and have recourse to prayer and the Holy Mass; she lives a very sinful lifestyle.
I'm sorry if the video is bad, I did not watch it.
