Who did it ?
So was it Mathew alone who murdered his parents or do u think his wife Maritza was involved too?
tragic incident.
Have a look on the internet! There's heaps of information around. But to answer your question.
Matthew did it on his own and Maritza was charged with being an accessory or perverting the course of justice. She was given a suspended sentence. All this was proved in court.
The last movie I watched was: Clerks II
