(AP) — Prosecutors have dropped a charge against a Lincoln man accused of doctoring a lottery ticket.

Jonathan Tonniges had faced a 20-year prison sentence if convicted for what his fiancee said was simply a practical joke.

Tonniges was charged after his fiancee went to a lottery office with a ticket she thought was worth $35,000. Workers told her it had been altered with a permanent marker, and the woman said she accepted that explanation and left. But workers called police.

The woman says Tonniges was playing a practical joke and that she never tried to cash the ticket. She simply asked about its value.

Lancaster County Attorney Joe Kelly said on Friday that he dismissed the case because there wasn’t enough evidence to convict Tonniges.
