A teen has been charged in connection with the murder of Stuart Walker, the BBC reported.

Walker is the 28-year-old openly gay bartender from Cumnock, Scotland who suffered a horrific attack that took his life on Saturday, October 22. His partially clothed charred remains were found on the side of the road.

Eighteen-year-old Ryan Esquierdo on Monday was formally charged with murder and theft. He appeared in private at Ayr Sheriff Court, but made no plea.

Police have previously said they could not rule out that Walker was the victim of a homophobic attack.

Chief Superintendent John Thomson of Strathclyde Police said: “I can confirm it was a very violent and sustained attack on Stuart. I do not believe at this stage that this was a random attack. There may be the possibility he knew his attacker or attackers.”

British Prime Minister David Cameron sent his condolences to the Walker family and called on the public to help in the case: “The police cannot solve crimes without the help of the public and I hope everyone will cooperate in the best way they can.”
