A man stabbed his son-in-law to death in a Queens apartment on Thursday night, police said.

The unidentified suspect got into a fight with Travis Ford, his 31-year-old son-in-law, at about 8 p.m. on 139th Street near Main Street in Briarwood, cops said.

He then grabbed a knife and stabbed Ford in the stomach and face, authorities said.

Ford was rushed to Jamaica Hospital and pronounced dead, cops said.

A neighbor who did not want to be identified said there was constant fighting from the apartment prior to Thursday’s killing.

The father-in-law was arrested by cops at the scene. Charges against him were pending Friday.
