Out of state buyer has a squatter

[Precious Thompson]

Good morning everyone, I would appreciate some advice on how I can do about helping an out of state landlord on what advice I can give him? He has a squatter in the property for about 15 days he in California property is in pa . I did research on the eviction process here in pa, is there anyway I can help him, he said the tenant is willing to leave doesn't have a place to go, he evening willing to fund  room for rent him, it worst came to worst and he had to evict could i take is place in court since he pretty far away?

Thanks in advance
