The FBI is warning a Naugatuck man accused of killing his own daughter that their search for him will not stop until they find him.

Christopher Francisquini is accused of stabbing his 11-month-old daughter Camilla to death.

"We stand here today united," said Assistant Special Agent Michael Butsch with the FBI Office in New Haven.

The FBI held a news conference Thursday outside its New Haven office, joined by state police and Naugatuck police.

The FBI has been working around the clock, but it is now hoping the media can push the word out about their No. 1 suspect, 31-year-old Christopher Francisquini.

"He may be contacting family, friends or acquaintances seeking assistance, and he may travel to places with which he is familiar," said Butsch.

Francisquini allegedly stabbed his young daughter Camilla to death on Nov. 18. She would have turned 1 year old this Saturday. Police say she was found in a state of dismemberment at Francisquini's home on Millville Avenue in Naugatuck.

"This kind of a loss tears a hole in our community and leaves us all searching for questions and answers about how something as terrible as this could happen," said Naugatuck Police Chief Colin McAllister. 

"Camilla was one of our own.  A happy beautiful little girl whose life was taken needlessly," said Butsch.

Police say Francisquini was last seen recently in surveillance pictures on Quinnipiac Avenue in New Haven. They say he should be considered armed and dangerous.

"He may exhibit increasingly erratic, unpredictable behavior and we want to ensure everyone's safety.  He may have also attempted to change his appearance such as shaving his beard, cutting his hair or hiding the very distinctive tattoos on his neck and on his hands," said Butsch.

Francisquini has a tattoo of CME with flames on the right side of his neck, a tattoo of Milla with stars on his right hand and a tattoo of a clown on his left hand.

"Until this apprehension is done our Naugatuck investigators as well as our law enforcement officers will be wearing pink to find justice for Camilla," said McAllister.

There is a GoFundMe that has been setup to help pay for Camilla Francisquini's funeral. It has already raised over $10,000.

The FBI has increased its reward to $25,000 for any information leading to the arrest of Francisquini. 

There are billboards on Interstate 95, Interstate 91 and Interstate 84 in the state as well as other states nearby. 

Police say Christopher Francisquini already has an extensive criminal history, which includes assaulting a police officer.

Anyone with information about Francisquini's whereabouts is asked to call the Naugatuck Police Department at 203-729-5222 or the FBIat 1-800-CALLFBI (1-800-225-5324)
