Detectives investigating the death of 29-year-old Mingzi Yang in Lincoln have charged a man with her murder.
Wai Hong Tsang (33) from the Grimsby area, has been charged with murdering Ms Yang.
He appeared at Lincoln Magistrates Court on the morning of June 23, and at Lincoln Crown Court in the afternoon on the same day.
The man has been remanded in custody until a plea and case management hearing in September.
Mingzi Yang moved to the UK from China in 2008 and is believed to have lived at the address on Sincil Bank for around two and a half years.
She joined the English for Speakers of Other Languages programme at Lincoln College in September 2013.
DCI Martin Holvey, who is leading the investigation, said: “Since the death of Mingzi we have spent a great deal of time trying to build up a picture of her life and we still greatly need the assistance of the public with that task.
“I would directly appeal to anyone who knew her, even if it was only very casually, to get in touch with officers to help us construct a greater understanding of the life she led since arriving in the UK in 2008.
“College friends, people she knew who lived in the area, any individuals from the Chinese community – your information could be exactly what we need.
“We are also really keen to hear from anyone who saw Mingzi on the morning of June 17. Please contact Lincolnshire Police with that information.
“It may not seem to be important but could prove vital to this investigation.”
Anyone with any information is asked to contact Lincolnshire Police on 101 quoting incident 181 of 17/06/2014.
