It depends on the multiple crimes. If they are committed as part of the same agreement or relationship between conspirators, there is only one count of conspiracy. (i.e. conpiring to purchase and sell a lb. of cocaine is one conspiacy, to distribute, and not two conspiracies - to buy and then to distribute.) If there are seperate agreements (i.e. two weeks later, they again agree to purchase and sell another lb.) then there are two conspiracies.
It's a really long hypo. The gist (the part that is confusing) is as follows:A, A2, and P agree to break into V's house at night (burglary is a given) to threaten V. A2 assists in the planning but doesn't go along. Unbeknownst to A, P brings a gun in to make sure that V "gets the message."While they are threatening V, V makes a provocative statement to them. P flips out and fires at V, but misses.V fled in panic and jumped into his car, speeding away. He's driving recklessly and he tries to pass someone in front of him. He ends up swerving off the road into an enbankment. A2 (from earlier) walks by and sees a figure slumped over the wheel. He knew whose car it was but he kept walking. V died the next day.
