What Pankaj did was a disgrace to all...Heard a lot of Nepalese student @ University of Texas at Arlington, are facing difficulties due to this incident.  His action is punishable, there is not doubt.

The question is why would the store owner report it....  The story goes, he asked Pankaj Joshi for the ticket to cash it for himself.  PJ refused to this. I guess they could not come to deal. The owner never though PJ would cash the ticket on his own, with all the threaten he was given and also he was student with F1.  PJ cashed it, Owner got pissed and called the Lottery HQ.

What he did was not for justice but out of jealousy and greed.  Neither of them had any ethics....

Looks like the the ticket owner, was actually third in line to get the money...
