A man going through a divorce stabbed his mother-in-law to death, wounded his teen brother-in-law – then slit his own wrists and set their Queens home on fire on Thursday, cops and sources said.
The 27-year-old man allegedly knifed his 50-year-old mother-in-law and her 17-year-old son multiple times inside a house on Smart Street near 45th Avenue in Flushing just before 4 p.m., authorities and sources said.
The victims were taken to NewYork Presbyterian Hospital, where the gravely wounded mother-in-law succumbed to her injuries and the teen was listed in stable condition.
The alleged attacker was also hospitalized and placed in police custody, according to the sources.
A dozen FDNY and EMS personnel responded to the scene, with the flames knocked down by around 4:40 p.m., the department said.
Fire marshals were responding to the scene, according to the FDNY.
