FBI spokeswoman Laura Eimiller says two hikers found the body of 35-year-old Steven Ivens on Monday in a wooded area behind a Burbank church. Ivens' gun was found near his body.
The cause and time of death will be determined by the Los Angeles County coroner's office.
Authorities say Ivens was being treated for depression and was said to be distraught at the time of his disappearance.
A massive air and ground search was unsuccessful after Ivens walked away from his home May 10 with his keys and his service weapon. His wife, Thea, later made a public plea for him to return home.
Ivens is survived by his wife and 2-year-old son.
