Was it anything like this?
The description says.
This is not a highend pistol crossbow as you can guess by it's low cost. However, it is a great starter for practicing and getting aquainted with crossbows. Pistol crossbow can be used for hunting small game and getting rid of vermin. Please follow local hunting regulations if using for hunting.
There looks to be no way to put broadheads on those bolts. So I guess the poacher was using field points.
