A man in Taiwan allegedly killed and dismembered his 27-year-old girlfriend before hanging himself, in a grisly murder that has gripped headlines on the island.

The man, 28-year-old boxing coach and former mixed martial arts fighter Gary Chu, is believed to have murdered Ms Huang I-Min for lying to him that she was a virgin, reported local news outlets.

Ms Huang's body was found dismembered and the parts separated into eight plastic bags, reported Taiwan News on Wednesday.

The National Taiwan University graduate's remains were discovered after her brother contacted the police on May 26, saying she had been missing for a week. Police then searched Chu's apartment and, after reviewing surveillance footage, found that she had entered her boyfriend's flat on May 20 - the day she was last seen alive. Two days later, Chu was spotted again in footage leaving his flat, carrying seven trash bags.

After a search, police announced on Sunday that they had found the seven bags containing Ms Huang's dismembered remains buried in a garden. On Wednesday, police said they found an eighth bag containing her left thigh. But her internal organs are still missing.

On Monday, Chu's body was found hanging from a tree near a hospital in Xinzhuang district. There was a suicide note with the message: "She wronged me."
