This surveillance video shows newlyweds Bhadreshkumar and Palak Patel for the last time as husband and wife.

The newlyweds moved from their native country of India to begin their  marriage in the United States—eventually settling in Hanover, Maryland,  where they each took jobs at a donut shop.

On April 12, 2015, the couple was working side-by-side on the night shift.

Palak was on the phone telling a family member that she wanted to go home to India.

The pair’s visas had expired.

With family still on the line, Palak and Bhadreshkumar walked to a  back room, where Bhadreshkumar stabbed his wife over and over again.
