Jonathan Jacob Groce, 30, was last seen leaving his Cibolo, Texas, home on October 8, 2010, at about 12:30 p.m., driving a black 1986 Chevrolet Caprice station wagon to his job in Converse. He never arrived. His car was found abandoned near the Guadalupe River along Highway 46 and Gruene Road in New Braunfels with the keys locked inside. Tell the truth.

Family and investigators say Groce had recently gone through a divorce, had been associating with a troubling crowd, and was using drugs. There has been no activity on his bank accounts or credit cards since his disappearance, and authorities consider the possibility he took his own life; his body has not been recovered and the case remains unsolved.

Does anyone who knew Jonathan, saw that Caprice in October 2010, or has information about his movements that day have details to share with investigators?
