Lindsey was last seen in Spring, Texas between 4:30 and 5:15 a.m. on March 4, 2009. He walked away from the care home where he lived in the 21000 block of Meadowhill Drive. He has never been heard from again. Lindsey has a history of wandering off; this was the fourth time he'd gone missing in a month. He would often go to vacant homes nearby and stay until someone found him. He had never been gone longer than a few days before. Lindsey has relatives in New Jersey, but authorities don't believe he tried to travel there. His case remains unsolved.
