Diaper debt sparks slay

A bitter Facebook fight over a $20 diaper debt turned deadly for a Brooklyn woman who was stabbed to death in her home by her boyfriend’s sister, police said yesterday.

The blood-soaked body of Kamisha Richards, 22, was found Monday night on the floor of the East New York apartment she shared with her boyfriend, cops said.

Her boyfriend’s sister, Kayla Henriques, 18, was arrested and charged with second-degree murder. Cops said Henriques confessed to the crime after being advised of her rights.

Friends and relatives of the victim and the suspect said the longtime friends had fallen out over money Richards had lent Henriques to buy diapers for her 10-month-old baby.

Richards, according to friends, became upset when she learned that Henriques had used the money for something else, and had yet to pay her back.

The two took their dispute to Facebook, where they traded stinging snipes for two days before Henriques allegedly plunged a steak knife into Richards’ chest.
