Please help answer the following question

Bart and Betty are heroin addicts. They need money for their next fix. They decide to steal from their neighbor, Mr. Green. They agree that this has to go without any violence because they are on parole and they don't want to go back to prison. Betty, a former prostitute, says Mr. Green likes her. He is always inviting her into his apartment and making advances toward her. So Betty offers to go to Mr. Green's apartment and seduce him into having sex with her. She tells Bart that he will wait outside the apartment until he hear Betty start making loud noises during the sexual encounter to signal Bart that it is safe to come into the apartment and search for items to steal.

Betty goes and knocks on Mr. Green's door. Mr. Green immediately invites Betty into his apartment. Betty is able to quickly seduce Mr. Green and they begin to engage in a sex act on the bed in the back bedroom. After a minute or so, Bart hears Betty making loud noises that sound sexual in nature, so he enters the apartment. Bart can see into the back bedroom where he confirms that Betty has Mr. Green occupied, so he begins to search the rest of the apartment for things to steal. Bart searches a desk and pulls out some cash and puts it in his pocket. He also grabs a big screen TV and heads out the door. Bart stops at the bedroom door and signals to Betty that he are good to go.

He waits outside the bedroom door to be sure Betty gets free from Mr. Green. Betty gets up to get dressed and leave. Mr. Green asks her if she wants to have more sex. Betty picks up a lamp and hits Mr. Green over the head, killing him instantly. Bart screams, "Why did you do that??!!" Then both run out and back at their apartment. The two split up the proceeds and spend it all on heroin.

What crimes, if any, has Betty committed, has Bart committed? do NOT have to discuss Conspiracy. Michigan State the elements and facts that support ?
