Joshua was last seen in the kitchen area of his family's mobile home in the 2600 block of Savannah Hills Circle in New Braunfels, Texas between 8:00 and 8:20 p.m. on February 4, 2011. He lived with his parents and his older brother, and his mother was eight months pregnant with a boy. His parents were hosting a party that night and there were nine people in the house, including Joshua. He disappeared sometime before 9:00 p.m. and has never been heard from again.

Joshua is described as a very mobile toddler, and the front door to his home didn't latch properly. Authorities initially believed he had wandered away. They conducted an extensive search of the neighborhood, but they found no sign of him and tracker dogs couldn't pick up his scent. If he had been without shelter, he couldn't have survived long; the night he disappeared, temperatures dropped to 19 degrees.

Because they were unable to find Joshua in the local area, investigators began to look into other possible causes of his disappearance. His parents said they believed he had been abducted and suggested a family friend as a possible suspect. The friend had visited the mobile home on the night of February 4 and left shortly before Joshua was discovered missing. He reportedly gave conflicting stories about that night and refused to take a polygraph test.

The circumstances of Joshua's disappearance are unclear. His case remains unsolved.
