SALT LAKE CITY — A Midway woman escaped a domestic violence situation over the weekend after writing “911” on her hand and quietly showing it to a repairman, according to police.

Grant Nielsen Eggertsen, 45, of West Jordan, was charged Monday in 4th District Court with aggravated kidnapping in the course of committing unlawful detention, a third-degree felony; trespassing, a class A misdemeanor; and assault, a class B misdemeanor.

On Friday, a locksmith was called to a home in Midway to change the lock on the front door. The man was changing a lock for a woman, “and on her hand she had 911 written and showed it to him,” according to a police affidavit.

The locksmith contacted police and told them there was a man in the house who stayed close to the woman the entire time, and that when the woman wanted to pay the locksmith using her phone, she had to ask the man for it, the affidavit states.

When an officer arrived at the house and knocked on the door, the woman “quickly opened the door and walked fast out the front door and stated that he was downstairs in the house,” the affidavit says.

The woman told police that Eggertsen, who has a key to her house, had arrived the night before unannounced, walked in and took her phone.

“She asked him to leave multiple times and he would not leave and he was holding her in her room against her will,” according to the affidavit.

Eggertsen also allegedly threatened to burn the woman’s house down.

The woman also sent two emails to undisclosed people asking for help, police said. The officer was shown both emails.

“I also observed the victim’s hand and 911 written on her hand,” the officer wrote.

In 2014, Eggertsen was convicted of an amended charge of attempted stalking. In that case, Eggertsen threatened to kidnap and kill a woman whose house he had driven by several times, according to court records.
