His wife, Rose, filed a missing persons report with the Los Angeles Police Department on Monday at 10 a.m, according to the site. She claims she last saw the 32-year-old on May 9.
"I can confirm that he's missing," an LAPD officer told People. "And, as of now, he is still missing."
The couple has been separated since January, according to court papers filed by Rose in February. At the time, she asked a judge to limit her husband's visitations with their 2-year-old daughter, Marlo, to eight supervised hours per week. She also asked that Stahl pass a test to prove that he hadn't taken drugs or alcohol in the previous 24 hours prior to seeing their daughter.
