Newly-filed court paperwork shows Jesse Conger, a Marine veteran reported missing in Arizona in August, is wanted by authorities in Utah.
The 37-year-old left his girlfriend's apartment in Scottsdale, Ariz. on August 14, and hasn't been seen since.
Records indicate he was due in court for a domestic violence-related case two weeks after he disappeared.
According to court records, Utah authorities obtained text messages in which Conger threatened to kill his ex-girlfriend. He is not facing charges for the threats, but for retaliation against his ex.
Conger's twin sister, Patricia, told KNXV she doesn't believe he is a danger to others, or that he's running from his charges. She said she just wants to find him, because he's not in his right state of mind.
Those who've organized search efforts for Conger say they plan to continue their search, regardless of news of the arrest warrant, KNXV reports.
Conger is known to have post-traumatic stress disorder and depression stemming from his time in the U.S. Marine Corps. His family said he did three tours of duty overseas.
A $30,000 reward has been offered for locating Conger, according to the "Find Jesse - Missing Veteran" Facebook page administered by Conger's family members.
Conger drives a silver Toyota Camry with Nevada license plate 696G03, according to the Facebook page. When he left the Arizona apartment in August, he did not take his phone, wallet, ID, or service dog, a post states.
"We believe he may have been suicidal, and we also believe he is paranoid and is possibly hiding," his sister wrote.
Conger is described as six feet, three inches tall and weighing approximately 200 pounds. He has brown hair, a brown beard, blue eyes, and numerous tattoos.
In the time leading up to his disappearance, Conger had made comments about committing suicide in the desert, according to a Scottsdale PD missing person bulletin. He left his girlfriend's apartment with only his vehicle and a firearm.
