Ashley Wadsworth, 19, was found stabbed to death in Chelmsford, Essex, on Tuesday after worried neighbours called police.
Her boyfriend Jack Sepple, 23, appeared at Colchester Magistrates’ Court today charged with murder.
The court was told he was discovered on his phone on a bloodstained bed next to Ashley’s dead body when police arrived.
Canadian Ashley was on a six-month tourist visa and came to Britain after meeting Sepple online, it was said.
Tattoo-covered Sepple spoke only to confirm his name, date of birth and address during the short hearing.
He was remanded in custody to next appear at Chelmsford Crown Court tomorrow.
Lovestruck Ashley shared a series of beaming photos on her Facebook as she explored London with Sepple.
Her Facebook revealed she was leaving her home in Vernon, British Columbia, to move to Chelmsford more than 2,000 miles away in November.
Photos showed the pair hugging outside popular tourist spots in London as she branded him “my bestie”.
In pictures shared on January 11, the couple have their arms wrapped around one another near Buckingham Palace and Big Ben in London.
Other pictures shared on January 18 by Jack’s mum show Ashley joined the family for a trip to the historic town of Rye in East Sussex.
Emergency crews were scrambled to the block of flats on Tuesday night after receiving reports of a domestic disturbance.
Sadly Ashley couldn’t be saved and was declared dead at the scene.
Police later confirmed they are not looking for anyone else in connection with Ashley’s death.
Her heartbroken big sister, Hailey Wadsworth, vowed to get justice for her sibling.
She wrote on Facebook: “My poor baby sister we will get justice baby girl I love you so much I miss you everyday your big sissy loves you.”
Ashley’s heartbroken friends in Canada have paid tribute to the churchgoing teen.
