Towed and squashed

I am an owner of a unit in a large block of units. My daughter is the tenant. I gave her a car so she could get her license. The car was parked to the side of a long driveway leading to the car spaces. Many cars park there seemingly legally as signage either end of the driveway indicates that there is no parking past a certain points. When coming home from work one evening she noticed the car missing. I attended the police station and reported it stolen. None of the other occupants seemed to know anything until her dad becames involved. Then one of the owners printed an email trail which indicated both the Strata Managers and several of the owners knew exactly what happened. The email indicated the car was towed at the request of the Strata Managers. Further, it read, at the time it was towed to the street, a Council Officer removed the plates(council have vehemently denied this saying they do not remove number plates) and stated it couldn’t be left on street as it was unregistered (council confirmed they would not have been able to determine this)
the email goes on to read Police advised to dispose of the car! So it reads the car was scrapped!!!! In the car at the time it was towed were several high priced items including a wedding dress ( strata managers have confirmed they have this item only) Strata Managers have stated to me they were advised it was an abandoned car. However if that was true why did they retain the dress? I can confirm no notices of any kind were placed on the car, no letter or any advice was received by either myself or daughter in terms of the car being parked there. It seems a far fetched story……. I am still trying to understand how this can happen. I would appreciate any advice in terms of who to contact first and who would be the best people to represent myself in this matter. Thankyou.
