LYNN, Mass. - State police issued an Amber Alert on Wednesday for four children taken with their mother from an apartment where another woman was found fatally stabbed.
The children range in age from 11 months to 3 years. All five are believed to be with the children's father, Rodlyn Petitbois, said David Procopio, a state police spokesman.
Essex District Attorney Jonathan Blodgett said his office was seeking an arrest warrant for Petitbois on a first-degree murder charge.
"At this point in time we believe Rodlyn is extremely dangerous and may be armed," Blodgett said.
Police in Lynn, about 15 miles north of Boston, went to the apartment early Wednesday after receiving a report of a stabbing. They found Greenland Etienne, 33, with stab wounds to her face. She was pronounced dead a short time later at Massachusetts General Hospital.
Blodgett said authorities believe there was a "social" relationship between Etienne and Petitbois but that link was still under investigation.
Police said Petitbois, 25, came to the United States in 1999 through New York. State and New York City authorities have been put on notice. The FBI and immigration authorities also are investigating, Blodgett said. Blodgett did not specify Petitbois' home country or immigration status.
Blodgett said Petitbois did not have a local criminal history. He had a government-issued photo identification but not a driver's license.
The mother of the children, Louna Eveillard, 26, may have a stab wound to her hand and may be wearing a bandage.
Blodgett said there was no indication she was an accomplice.
Blodgett said an earlier report of a 1992 white Buick Roadmaster being used in the abduction turned out to be unfounded.
The children were identified as: Ryan Petitbois, 3; Lyndsey Petitbois, 2; Lauren Petitbois, 22 months; and Roddick Petitbois, 11 months.
Authorities said they are not sure whether Petitbois and Eveillard lived together or what kind of custody arrangement they had for their children.
