HOUSTON >> A Texas man who went missing as a teenager in 2015 after last being seen walking his dogs in Houston has been found alive, police said Monday.

Police and firefighters found Rudolph Farias IV around 10 p.m. Thursday after getting a call of a person lying on the ground in front of a church in southeast Houston, police spokesman John Cannon said.

It was not immediately known where Farias had been the last eight years, Cannon said. Police investigators had not yet spoken with Farias, 25, who remained hospitalized.

“What we do know is at the time of his recovery, a good Samaritan located him unresponsive and immediately called police and 911. My son Rudy is receiving the care he needs to overcome his trauma, but at this time, he is nonverbal and not able to communicate with us,” Janie Santana, Farias’ mother, said in a statement.

In a tweet Monday afternoon, Houston police said it planned on speaking with Farias and his family on Wednesday.

The news that Farias had been found was first reported in a tweet on Saturday by the Texas Center for the Missing, which was handling public communications on behalf of Farias’ family.

“We do know when a loved one goes missing this is the day all families hope for and dream of — REUNIFICATION. We are thankful that Rudy has been found and receiving the care he needs,” the center said in a statement Monday.
