It's been nearly a month since an Edmond man disappeared.
According to those close to him, Bruce Jacobs’ last known destination was Arcadia Lake.
Investigators found his truck abandoned hours after he was last seen.
Several agencies including Oklahoma City Metro Search and Rescue have spent hours on foot, combing the areas where Jacobs and his pickup were last seen.
“I speak to my brother if not every day, every other day,” said Jacobs’ sister Rachel DiFatta.
After learning her baby brother Bruce Jacobs was missing, DiFatta left Mississippi and made a b-line for Oklahoma.
According to a missing person's report filed by Jacobs' girlfriend his camper was left at Arcadia Lake on June 16.
His pickup was found abandoned on the railroad tracks in Choctaw between Northeast 23rd and Northeast 36th.
“The railroad supervisor and his crew were notified there was a vehicle on the tracks,” said DiFatta.
Search crews scoured the area believing Jacobs may have gotten lost in the woods after he was forced to leave his truck behind.
“He drove a quarter of a mile on the railroad tracks to where he couldn’t drive any further and in the process of turning around got stuck,” said Brian Smith, Oklahoma City Metro Search and Rescue.
Jacobs’ girlfriend told police they had argued and that he may have turned to drugs.
And while his family admits he's gone off the radar before this time is different.
“He would contact me immediately if he was OK and it's been 28 days today, so, I know my brother is not OK,” said DiFatta.
Jacobs was last seen wearing this hat, a turquoise shirt, and cowboy boots.
He also has a distinctive batman tattoo.
“He's the most wonderful man. He's our batman. He beams light on us and we need him to beam his light,” said DiFatta.
Jacobs may have been overcome by heat.
Search crews ask anyone with property near the area to do a thorough scan of their land.
