Montgomery County police say a Silver Spring woman was fatally stabbed early Saturday, and detectives are questioning the victim’s estranged husband.

Police said Ana Ayala, 47, was found around 8:15 a.m. in the front seat of a vehicle in the parking lot in the 8600 block of Garland Avenue., Silver Spring. Ayala was suffering from multiple stab wounds and later died from her injuries at a local hospital.

Police said a witness told them that Ayala’s estranged husband, Hector Granados, 44, of the 8700 block of Barron Street, approached Ayala while she was in the vehicle. The two had a brief conversation, according to the witness, and Granados then allegedly stabbed Ayala and fled, according to a statement released by the Montgomery County police. Granados turned himself into police some four hours later and was being questioned by detectives.
