BOSTON (CBS) – Boston Mayor Marty Walsh said the city is mourning the loss of young mother Jassy Correia.

Correia was found dead Thursday, according to her family, after an exhaustive search. She was last seen alive early Sunday morning leaving a nightclub in the Theater District, where she had been celebrating her 23rd birthday with friends.

“A horrible tragedy for the city of Boston, a young mother, a young life,” Walsh said Friday before visiting the family’s home in Dorchester. “This young woman had a lot of ties here in Dorchester. She played sports growing up here; she has friends here; she’s raising a child … a little girl. It’s just really, really sad.”

Boston Police say Louis Coleman III, 32, of Providence, kidnapped Correia. He was arrested Thursday afternoon on a highway in Delaware. Correia’s family said her body was in the trunk of Coleman’s car. Police confirmed a body was found, but they are waiting for a positive identification.

“This guy … this guy is an animal,” Walsh said.

Jassy, who lived in Lynn, leaves behind a two-year-old daughter.

“The pain that we feel as a city right now is real as we mourn the loss of a young life that was taken too soon. My heart breaks for Jassy’s family and friends, and her young daughter,” Walsh said in a tweet Friday. “Together, let’s watch over one another. We are our brothers and our sisters’ keeper.”

Walsh also noted that this is the second case in two months where a woman was preyed on while out with friends. He urged caution.

“To people going out, whether young men or young woman, just be careful,” Walsh said. “Just be careful when you go out there. You just don’t know who’s out there preying on people, what the situation is.”
