Called several times, answered and told them i was given the number to the "authorities"... calls stopped.

Caller claims to be calling on behalf of Texas State Trooper. I was quite busy. He said he would call back but never did.

Received a call from this number. Didn't answer and no message left. Caller ID said "Liberty, TX".

If these people claim to be calling on behalf of the Texas State Troopers, I was told many, many years ago that law enforcement does not solicit donations over the phone. It is a SCAM!
