Richland Hills police have asked for the public's help in finding a 62-year-old man who hasn't been seen since Monday.
Investigators said Rocky Brown, who suffers from a number of medical issues, left the La Quinta Inn on Loop 820 at 8:42 a.m. that day. He was expected in Illinois on Monday evening.
Authorities tracked Brown's cell phone to an area about 90 miles southeast of El Paso, but ground and aerial surveillance has offered no clues to his whereabouts.
Brown had been driving a silver or gray 2004 Lincoln Town Car with Texas plates DW9-F998. He is described as a balding white male with a white goatee. He was believed to be traveling with a small Pug-Chihuahua mix dog.
