Grinning for the camera while holding a sign supporting her beloved American football team, the woman hardly looks like an assassin – let alone one operating in the UK.

Yet Aimee Betro, 45, was found guilty on Tuesday of travelling 4,000 miles from her Wisconsin home to carry out a 'hit' on a man in Birmingham.

Extraordinarily, the naive American received no payment for the shooting despite apparently struggling for money.

Her motive? She was prepared to kill for love after becoming infatuated with a British petty criminal she met through a dating app.

Betro, wearing a niqab to disguise herself, pointed a gun at her victim's head outside his home in Yardley and pulled the trigger.
