I don’t know the name of the movie, please tell me

The film is in English, not popular

The events of the film take place in a small town at night. The girl turned into a humanoid monster and began to kill everyone at night. The same girl, at the end of the film, turned the male policeman into her own kind (she got out of her mouth like a tentacle and she sent it into his mouth), and the policeman’s partner escaped. They broke into the police station, where the monster man failed to kill his former colleague, but the monster girl killed her. At the end of the film, she is hit by a car, and he is handcuffed and imprisoned.
