Pacific Grove >> Chad Hillhouse went on a drive on Aug. 13 after possibly having an argument with his girlfriend and hasn’t returned to his Pacific Grove home on 8th Street.

His mother last talked to him Aug. 10, but since he went missing, he has not answered phone calls and phone records show no trace of outgoing calls. By now, authorities said his phone appears to be out of battery.

“It is concerning that he has no credit cards to his name, and he has not accessed any money or any bank accounts,” his mother, Deborah Dahlinger, said.

In efforts to help find him, Hillhouse’s mother and brother have flown from out of state to Monterey County, but so far, they have no new information leading to his whereabouts. The last location where his phone was tracked was at Riley Ranch Road near Point Lobos.

“I thought this would be easier,” Dahlinger said in tears. “We are putting posters all over town.”

Hillhouse, 39, is described as about 170 pounds, with brown eyes, and a shaved head. He has a tattoo of a polo horse on the left side of his chest and a tribal tattoo on his mid-back. His mother said he loves the outdoors and is a very quiet, yet social person. He is very fit, she said.

He is a Navy veteran and has a history with depression. He did not fill his prescription medication for depression and anxiety on the day he went missing. He is believed to be at risk.

Dahlinger said he is known to frequent national parks and his favorite location in the county is Asilomar State Beach. He was last seen driving a 2015 silver Jeep Rubicon.

“He is a very bright, creative, artistic person,” Dahlinger said. “I just want him to know his mom and his brother, Jordan, are out here looking for him.”

If anyone has information about Hillhouse’s whereabouts please contact his mother at 808-557-7564 or email her at debdahlinger@aol.com
