Unfortunately you are not an independent witness in respect of the alibi and therefore, it has not got that much credibility although we don’t know when it was actually put out, only when it was discovered. What other prove does she have that she was miles away on the day and time of the incident?
You say that it’s likely that it was put there accidentally by her sister. How do you know that? Would your daughter be prepared to put her sister forward as the culprit? She doesn’t have do, I’m just asking.
She doesn’t have to accept fixed penalty and he can plead not guilty in court if she wishes.
What else would you like to know about this?
