The husband and wife were separated, and the husband was living with his stepdaughter in the 7300 block of 21st Street.
At 7:27 a.m. Saturday, the estranged wife, identified as Carmen Basulto (pictured), 43, showed up at her daughter's residence with two armed men, who forced the victim from the home at gunpoint, said Police Department spokeswoman Officer Laura Peck. The daughter witnessed the incident and called police.
Detectives took over the investigation and later located the victim, who was unharmed. Peck said Basulto was located and arrested Saturday afternoon on 24th Street.
Police are still seeking the two men who accompanied her. One is described as Hispanic, in his 30s and heavy-set. He was wearing a gray scarf, black sweater and a hood over his face.
The other man was described as a Hispanic adult, tall, thin and wearing a black sweater and hood over his face.
They fled in a four-door, white, 1990s model Honda.
Basulto was booked into Sacramento County Jail on suspicion of kidnapping, robbery, domestic violence, false imprisonment, and possession of a dangerous drug or controlled substance. Bail is set at $245,000.
