just add some ideas of mine, if u need some proof of evidence if you have time to act as a secret detective and take some pictures of the filipina girl with the family or husband,try to follow the filipina woman after work to find the house, or if they have a date to your friend try to follow her after they met, you can act or disguise face or whatever if you have time, or if you know the home of that woman try to hung out near the home some other day.
