After being reported missing more than three months ago, Carolyn Sinclair was found dead near a West End dumpster on the weekend.

Carolyn Sinclair, who was pregnant at the time she went missing in December, was due to deliver her baby this month.

Homicide officers are investigating her death.

"I'm so filled with anger and I don't understand how a human being could do that to another human being and to top it off, she had another human being growing inside her," said Amanda Sinclair, the victim's sister.

Family members put up missing person posters, trying to get tips to find Carolyn after she went missing in December. 

It's believed the body of Carolyn Sinclair, 25, had been at the location near a dumpster in the 700 block of Notre Dame Avenue for some time before it was discovered wrapped in plastic on March 31.

The head of Winnipeg's homicide unit said detectives have not ruled out any suspects, including those close to Sinclair. Police said they are looking into the possibility her lifestyle might have played a role in her death.

"That lifestyle would include the illegal use of drugs. It would have included working in the sex-trade industry," said Const. Natalie Aitken from Winnipeg police.

Officers are canvassing downtown drug houses the victim was known to visit.

"We believe we need information to come forward," said Aitken.

Carolyn Sinclair's family hopes her killer is caught soon. In the meantime, they're focusing on preparing to say goodbye.

"They gave us a choice if we wanted the baby and my sister to have separate caskets. That was heart wrenching to know the fact that the baby was still inside her," said Amanda Sinclair.The family plans to bury mother and child together.

So far, no arrests have been made in the case.

Anyone with information, or who may have seen Carolyn Sinclair after mid December, is asked to contact investigators at 986-6508, or Crime Stoppers at 786-8477.  

Carolyn Sinclair's loved ones are planning to hold a vigil on Tuesday, April 3 at 5 p.m. at the Note Dame Avenue location where her body was found. 

Amanda Sinclair said that she has had some measure of peace now that her sister has been found. 

"I feel my heart is at ease now because I know where she is and she can have her final resting place," said Amanda.
