Police in The Colony say a high school student has confessed to entering at least three homes in the Legends subdivision.
A half dozen homeowners in the area reported that someone had sneaked into their homes while they were asleep. Nothing was taken from the homes.
Anthony Huynh, 17, of The Colony, admitted to at least three of the incidents, police said.
Huynh had turned himself into police for an outstanding warrant on a charge of improper photography or visual recording that stemmed from an incident at The Colony High School.
During questioning in that case, he admitted to creeping in his neighbors' homes, including Ralph Cotto's house, police said.
Cotto said a man sneaked into his home on Jan. 14 and woke his youngest daughter.
"He touched her on the ear," Cotto said in an interview last month. "She thought that it was me, just playing around. She said, 'Stop. Daddy, knock it off.' And she heard the guy say, 'I'm not your dad.' Which, to me, that would make my heart sink if I heard something like that."
Police said Huynh entered the homes through unlocked doors and windows.
Resident Karen Leaman said wondered why Huynh was prowling but was relieved that he had confessed.
"It gives me peace that's he is off the street, but it makes me wonder why he actually did that -- and that doesn't give me peace," she said.
Huynh told police he never intended to harm anyone. He said substance abuse problems contributed to his behavior.
The Colony police said they are still investigating and determining what charges to file against Huynh.
Police also said that others are aware of the prowling and either failed to report it or assisted Huynh. Police are encouraging those people to come forward before possible charges are filed against them.
