Jean Weevens Janvier: Wanted for murder of Emile sisters in 2011.Jean Weevens Janvier: Wanted for murder of Emile sisters in 2011.US Marshals are teaming up with Boston Police to find a Dorchester man who has been on the run since he allegedly murdered two sisters in their Harlem Street apartment in Nov. 2011. The United States Marshals Service is offering a reward for tips that will lead to the capture and successful prosecution of 32 year-old Jean Weevens Janvier, a naturalized US citizen who was born in Haiti and who is the only suspect in the killings of Stephanie and Judith Emile.

Janvier was indicted in the double murder by a Suffolk County Grand Jury last April. Prosecutors said that Janvier had been in a previous romantic relationship with Stephanie Emile, 21, who was found shot to death alongside her sister, Judith, 23, in their Harlem Street apartment on Nov. 14, 2011. When police responded, a toddler was found in the apartment with the two deceased sisters.

“We believe this defendant fled the charges and the country in the aftermath of Judith’s and Stephanie’s murders,” District Attorney Daniel Conley said in a statement at the time. “We’re currently working with Boston Police, the US Marshal’s Service, and other law enforcement agencies to apprehend him and return him to face justice in a Suffolk County courtroom.”

In a statement issued to the Reporter this week, the United States Marshals Service— the federal government’s primary agency for capturing fugitives— appealed to the public for their assistance.

“Janvier is originally from Haiti and is believed to have fled following the shooting,” said the statement. “This investigation has been ongoing since November of 2011 and law enforcement is offering a reward to anyone who has information which directly leads to the arrest of Jean Janvier.”
