If a conjoined twin committed a crime but the other twin was innocent

How would the jail sentence work? Do they both gotta go to jail even though one is innocent? Is the other twin treated as an accomplice since they were probably there when the crime was committed? 🤔 Like "OUR hand stabbed that guy so technically WE committed this crime"

My lady just asked me this question & it sparked an interesting conversation. So I thought it'd make an interesting thought here... or a weird one. But that's SW's theme so hey 🙃
