A woman was fatally stabbed and her teenage son was badly hurt after her beau allegedly attacked them with a knife Saturday morning in the Bronx, cops said.
Yesenia Hall, 42, was stabbed in the neck and torso and her 16-year-old son in the neck and back around 6:30 a.m. in their apartment on Sherman Ave. in Highbridge, according to police.
The 45-year-old maniac who allegedly attacked them changed his clothes after the bloodshed and fled, authorities said.

The suspect was last seen wearing a neon vest and a hardhat at a construction site at 163rd Street and College Avenue, cops said.
Police said the dispute was domestic in nature.
A trail of blood stained the floor from the hallway outside the apartment to the building’s front doors, which included a red smear.
Family members clamored to get into the apartment but were held back by police.
“Oh my God, I want to go in there,” said one woman.
Relatives left a short time later carrying suitcases. One woman held a puppy wrapped in a brown blanket close to her chest.
Neighbor Shanae Headen, 33, said she was woken up by a commotion.

“I heard a lot of movements like somebody was thrown, you know, to the wall or something or somebody was moving furniture or something,” she told The Post.
“I heard [someone] saying … ‘No, no, no, no,’” she recalled, noting that the voice didn’t sound like an adult. “Maybe it was a teenager saying that.”
