Family members of a missing Brossard woman have arrived from China to search for their 42-year-old sister.

Jian Ping Li and her six-month-old baby went missing about 11 weeks ago.

Li’s sister, Jian Ying Li, is holding out hope that the 42-year-old mother is alive, but Li’s brother, who is a police officer in China, isn’t as optimistic. He believes the case should be a criminal investigation and not a missing person’s case. He also says that Li and her husband were having marital problems prior to her disappearance.

Longueuil police searched Li’s home and nearby parks and rivers. They say her husband is cooperating with the investigation. “We still consider it a disappearance case,” said Longueuil police spokesperson Mark David. “Of course all hypotheses are being looked at, but nothing indicates right now that it is criminal.”

Police also spoke to members of Li’s church and her co-workers. All of Li’s belongings, including her car and wallet were left at home. The only thing missing is Li’s Chinese passport.

Police have received about 90 tips from the public, but none have materialized into any leads. They are still asking the public for help.

Both the RCMP and Interpol are involved in the investigation.

Li’s brother and sister plan to stay in Canada until she is found.
