NEW BRAUNFELS, Texas -

It's been three years since an 18-month-old boy disappeared from his parents home in New Braunfels.

New Braunfels police said on Tuesday that the disappearance of baby Joshua Davis Jr. is still an open case.

"We still receive tips that come in," said New Braunfels police Capt. John McDonald. "Some of them are tips we have heard, but we still treat them as new tips."

Joshua Davis Jr. disappeared on Feb. 4, 2011. That's when he was last seen inside his home in the 2600 block of Savannah Hill Circle.

McDonald said they have already talked to the nine family members and friends that were there that night, including the toddler's parents, but said there are a few people that are not cooperating. He also said they have repeatedly searched the area. 

"From our standpoint, the child was there and then in a very short window, the child was not there," said McDonald. "Looking at the case from the beginning to end, some people have been less than truthful."

This month Comal County Crime Stoppers is upping the reward for any information on this case to $7,500.

"Right now that's what we're working off of," said McDonald. "So, we are asking anyone with information to come forward."

The Comal Crimestoppers line is 830-620-TIPS or 800-640-8422.
