Hi all I'm new here.....what about the death of Terri Burhoe on 7/11/81?

I've done some digging on this, apparently it was committed by 4 people instead of just the one guy...Butchy Doe was said to have been involved too....they killed her at the "terminals"(?) and then threw her body in the trunk and tried to burn it where it was found at the park..
Any info would be great....
