Francisco Javier Deleon, 31, is suspected of killing 51-year-old Robin Ward at a cottage in the 100 block of Almond Avenue on Thursday evening, Napa police Capt. Jeff Troendly said.
A resident who lives at the property on Almond Avenue notified police of the murder around 4:15 p.m. Friday, Troendly said.
Troendly said Deleon and Ward were acquaintances, and that the stabbing happened during a dispute over a personal matter.
Deleon was arrested at 4:30 a.m. Saturday at a home at 1042 Nightingale Drive in Fairfield, according to the Napa County jail booking log. He is being held in jail on the murder charge and a parole hold.
Deleon, a transient, knew a resident at the Fairfield address, Troendly said.
