My question involves a child custody case from the State of: NY

My child went for a visit to NCP’s (father) house this weekend. Visits have been sporadic the past 3 years. The schedule we have set by the court is Saturday at 2 until Sunday at 2 every other weekend. The past three years NCP has asked for Sunday’s noon to 5. It has not been every other Sunday, about once every six months NCP will call to visit. This past visit our 10 year old son reported that alcohol and cigarettes were offered to him multiple times by NCP which then made him feel very uncomfortable. The relationship is already strained due to NCP’s inconsistency. I have already contacted CPS and they began investigating yesterday. Is there anything else I should be doing. Thanks.
