A man was arrested in Ogden on Saturday after allegedly stabbing his ex-girlfriend and kidnapping her niece in Midvale on Friday evening.

A 4-year-old was rescued after an Amber Alert was issued for her alleged kidnapping on Friday evening, FOX 13 reported.

The investigation began around 7:30 p.m. Friday when the ex-girlfriend of 20-year-old Jonathan Moises Wuanloxten Hidalgo called him for a ride in the area of Tuscany View Drive and Bingham Junction Highway. Police say he picked up the woman and her 4-year-old niece, then stabbed the woman, dragged her out of the vehicle, and left her on the side of the road as he drove away.

The woman, who is also 20 years old, was still hospitalized in critical condition as of Saturday morning.

Her 4-year-old niece was still in the car as Hidalgo drove away, according to Salt Lake County Sheriff Rosie Rivera. An Amber Alert was then issued around 9:10 p.m.

Shortly after the alert, a woman called police and said she found the girl on the side of the road, not far from the stabbing incident.

When FOX 13 News reporter Spencer Joseph arrived at the scene, the woman asked for help in connecting with police after finding the child. FOX 13 photojournalist Richard Bork captured the moment the girl was taken by a police officer and placed safely inside an SUV.

Rivera said officers found Hidalgo’s vehicle abandoned on the side of I-15 near 3300 South.

“This is a very violent crime,” Rivera said Friday night. “Somebody that would just stab someone, leave them in the streets, and then drop off a child in the near area in this weather, in the dark ... he needs to be caught.”

Hidalgo was eventually located and arrested Saturday in Ogden, near 24th Street and A Avenue.
