The remains of a missing man's car were found in a burned out garage in Gary, Ind., over the weekend, several days after Chezvon Jones disappeared.
The discovery increased the frustration Jones' father feels over the pace of the missing person's case.
"They're not doing their job," said Larry Jones.
Surveillance video shows the 30-year-old man outside a Gary clothing store on July 2 as he got into his cream-colored Cadillac with two other men on July 2. He hasn't been seen since.
"I told the detective today, I said, 'Have you looked at the whole tape?' He said, 'No.' I said, 'You look at the whole tape you can see what happened to my son," the elder Jones said.
The vehicle was found not far from a canal not far from an industrial area on the city's east side. Divers for the past two days have gone back into the canal looking for a body or evidence of a crime. Neither has been found.
Jones' family and his friends returned to the area on Tuesday to continue their own search. They believe the father of three has been kidnapped and said the discovery of the vehicle is a discouraging sign.
"Nothing good. If they had to burn the car it couldn't have been -- it wasn't that serious. Whatever happened it couldn't have been that serious for them to do whatever they did to him," said Jones' friend, Howard Murdoch.
The family has circulated fliers hoping that someone will recognize the man and have some information as to what happened to him.
"We're out here every day. We're searching. We're looking. I'm not going to stop searching until I find my son," said Venus Hampton.
