Mary:
Would your friend be interested in an investigation? I know lots of ghost hunters in various parts of the country, and they are all too happy to do an investigation, free of charge. Their point is to get evidence. Although I cannot offer that they will do anything to get RID of the energies, some groups do offer some solace and help in the way of counseling, excorcisms, etc.
My advice for your friend to make this thing go away is to take sage weed, bundle it up, let it dry, and then set it on fire and put it out, allowing only the smoke out. You can take it from room to room and tell the energies to leave. Another thing she could do is a cleansing. This can be done with a deacon, or rabbi, or pastor, and he will move room to room and say a prayer. I don't know if that will work, since I've never actually been involved with a haunting where they wanted it to leave!
I do know that when I was going through my divorce, the JW's sent over elders to pray in each room of my house to make the evil spirits go away, and my Mother burned my tarot cards with gas. She said that my eyes were like a shark's eyes.... no feeling or emotion, until the cards were burned, then I went back to normal. But I think she was just being rediculous, and imagining things. I actually liked doing Tarot cards, I made a lotta $ doing that.
I don't do them now, of course, and doing a Ouija board would be beyond my scope of play.. but maybe your friend could avail herself of things that are available.
