Rent was sent in the mail with cash and now lost

[Kevin N.]

My tenant claimed she had put cash in the mail and after 10 days I still haven't received it.  I rent to a low income area. In the lease it stated i accept cash and money order. It's not on the lease but I also told them verbally that if it's cash then i would need to pick it up (my house is 10 minutes away).  she claimed she can proof that on the 1st the rent amount was taken out of her checking account. There is no tracking for the mail she sent or sent receipt. She keeps arguing that because i'm responsible for the lost of rent because the lease stated that I accept cash in the mail. If I file for eviction, do you guys think i can win in front of the judge?
