$23.$ Assume the same facts as set forth in Question $22,$as well as these additional facts: Carol and Boris jointly own $23$ Elm Street. After being struck by the taxi driven by Alice, Carol dies instantly, but Boris dies after a week in the hospital. After Boris$$s death, who now owns $23$ Elm Street? $($NOTE: An $$heir$$ is a person legally entitled to the property of another on that person's death.$)[$The facts from Question $22$ are as follows:$$While pedestrians Carol and Boris are crossing the street, they are struck and killed by a taxi driven by Alice. Alice is an employee of ABC Taxi Company $($ABC$)$ and, at the time of the accident, Alice was working for and driving a taxi owned by ABC. Boris and Carol$$s families are suing Alice and ABC for negligence and for wrongful death. These events occurred in a contributory negligence state.$]$
