One woman was killed and another injured when they were attacked with an ax early Saturday in a New York City apartment where cops found a small child who was unharmed.

Police found the dead woman partially decapitated after being called to the apartment in Brooklyn around 1:30 a..m., the New York Post reported. The victim was in her 20s.

The injured woman, Angela Valle, 21, was bleeding heavily when she stumbled out of the apartment and flagged down an Uber driver to take her to the hospital, the paper reported. The Uber driver called 911 instead. Doctors say she was critically injured.

Police said the child, a 4-year-old girl and Valle's daughter, was taken to the hospital for evaluation, according to the Post.

Sources with knowledge of the case told the Daily News the yellow-handled ax still had an orange price tag on it when police found it in the building’s trash compactor.

“There was an ax? That’s crazy," a rattled resident of the building told the paper, which also reported that Valle and the victim were related.

The killer may be Valle's ex-boyfriend, NBC 4 New York reported, citing law enforcement sources.

Investigators believe the man went after the two women with the ax after an argument escalated, according to the station.
