SALT LAKE CITY — A Magna man already facing multiple charges for allegedly violating a protective order has now been charged with aggravated kidnapping.

Jon Franco Mandujano, 18, was charged with the first-degree felony Monday in 3rd District Court. In addition, Mandujano is also charged with aggravated assault, a third-degree felony, assault on a police officer and four counts of violating a protective order, class A misdemeanors; damaging a phone, threatening violence and interfering with an arresting officer, class B misdemeanors.

Mandujano was arrested and booked into the Salt Lake County Jail on Oct. 31 for investigation of assault and unlawful detention of a minor, according to jail records.

While incarcerated, Mandujano called his girlfriend — the mother of his child — multiple times telling her "don't show up" and "don't go to court" in relation to his pending criminal case, according to charging documents.

Likewise, when Mandujano was out of jail, he continued to call and text her, asking her not to testify in court, the charges state.

Then, on Feb. 2, Mandujano went to the home where his girlfriend was staying under the pretense of dropping off their child, according to police. Instead, he forcefully took the woman and kidnapped her, according to the charges.

Mandujano picked up the woman, carried her to his car, put her in the driver's seat, then sat on top of her as he drove, the charges say. The woman said she tried to get the attention of police officers as they passed a traffic accident by honking the horn.

"The defendant told her to shut up and that they were going to die right now as he turned the volume up on the radio really loud and drove at a high rate of speed," the charges state.

Mandujano then drove to a field where he allegedly threatened to kill the woman.

"The defendant told (her) that he brought her to the field to kill her, that nobody was ever going to find her and that he had a shank underneath the seat," prosecutors allege in the court documents.

Mandujano choked the woman, bit her on her shoulder and placed a blanket over her head while telling her "that he didn't want to get blood spatter all over his car," the charges state. After the assault, Mandujano allegedly took the woman to his parents' house and carried her into his bedroom.

On Feb. 4, police investigating the missing woman's case went to Mandujano's house to arrest him. He resisted, tried to climb out a window, and then fought with officers, the charges state. Two officers suffered minor injuries while trying to arrest him.

Once booked in jail, police say Mandujano again called his girlfriend three times that same day.

Monday's charges come on the heels of two other cases involving Mandujano. On Thursday, he was charged with three counts of witness tampering, a third-degree felony, and five counts of violating the terms of his jail release, a class A misdemeanor.

On Jan. 24, he was charged with 11 class A misdemeanors: one count of witness tampering, and 10 counts of violating the terms of his jail release.
