Not a lawyer. By the letter of the law, yes.
They had to jump the fence - presumably the gate was secured - in order to get to the house. Further, they walked around the property looking for the owner. This looks to anyone without more knowledge, very much like trespassing.
Just my 2 cents, I'm not trying to defend or accuse anyone.
Only yesterday I listened to the whole 'Contractual Obligations' album for the first time in probably 20 years.
