Ms Chapman's relatives told Sky News' US partner network NBC News the 46-year-old had been married to Patrick for a few months, and they had been in a turbulent relationship for years.

Her sister Nicole Marshall said: "We were shocked because before that it was an on-and-off relationship. It was rocky, we were aware of that."

The Duchess of York, Sarah Ferguson, said she was "shocked and saddened" by the news.

In a post on Instagram, she wrote: "Jenean was loyal, hardworking, beautiful and fun and my heart breaks for her family and friends. I heard from her just a couple of months ago and she seemed so happy."

The duchess added that she was making a donation so her family could pay for legal and funeral costs, and repatriate her body to New York City.

A possible motive is unclear, and Patrick remains jailed on a $100,000 (£82,000) bond.
