Trent Jennings: Police launch manhunt for 38-year-old who stabbed sexual partner to death 20 years ago

A police hunt is underway for a man who stabbed a sexual partner to death during a drug-fuelled gathering more than two decades ago.

NSW Police raised the alarm on Friday about Trent Jennings, who was last seen on the Central Coast on Wednesday evening after failing to return to a mental health facility.

Members of the public were told not to approach the 38-year-old and instead to call Triple Zero immediately if they saw him or knew where he could be found.

He is wanted on an outstanding warrant and was last seen at a motel on The Entrance Road near The Entrance, police said.

Jennings was previously ordered to remain in a psychiatric hospital indefinitely after stabbing 32-year-old Giuseppe Vitale to death in 2003.

The then 18-year-old met Mr Vitale online and the pair met up for casual sex before Jennings tied up the older man and stabbed him in the neck.

Jennings was found not guilty of Mr Vitale's murder on mental health grounds in 2005 and was held in a hospital.

Six years later he made headlines again when he disappeared from Morisset Hospital near Newcastle before fleeing in a stolen car belonging to another man he met online.

Jennings was jailed for a minimum of 18 months for the theft after tying up the man during a consensual bondage session in a Sydney apartment.

Police are searching Sydney city center and other areas where he is known to spend time, including the Central Coast, Cumberland and Sutherland Shire areas.

He is described as a white individual, approximately 175cm tall, medium build, with short brown receding hair and a scar on his right hand.

Jennings was last seen wearing prescription glasses, a blue shirt, navy blue shorts, blue runners, a black and gold watch and a black backpack and a white tackle box.
