New Haven police are searching for a woman who is accused of setting her boyfriend on fire and causing extensive injuries.

Medics were responding to a home on Blatchley Avenue on Thursday to investigate a domestic dispute when the call was updated to an assault by burning, police said.

When crews arrived at the home, they found the victim, screaming in pain. He sustained burns to about 40 percent of his body, including his face, arms and torso, and some of his skin had burned off.

He told police that his girlfriend, Mayra Crespo, 46, of New Haven, had thrown alcohol on him and lit him on fire inside their apartment, police said.

The man was rushed to Yale–New Haven Hospital and he remains in critical condition at the Connecticut Burn Center at Bridgeport Hospital.

Police are searching for Crespo, who is wanted for first-degree arson, assault in the first degree, reckless endangerment in the first degree, second-degree breach of peace and violation of a protective order.
