Father takes search into his own hands, says police haven't done enough for his missing Black son
Robinson hired Jeff McGrath, who said he downloaded the Jeep's so-called black box and allegedly found things that concerned him.
"
So [Daniel] went missing anywhere from 9:15 to 9:45 in the morning, and the Uconnect tells us that the airbags blew at about 1:00 p.m. So there's a time gap there," said McGrath.
"I don't know if somebody is joyriding in this car; found it and decided they wanted to crash it. If somebody was trying to make it look like somebody was injured or died in this vehicle. I just don't know what happened," McGrath added.
McGrath said he reached out to the Buckeye Police Department to share his findings, but said he's been met with difficulty.
"I have relayed all my information to them. I don't think they want to hear what I have to say," said McGrath.
Authorities have maintained an "open line of communication" with the Robinson family and their private investigator, the Buckeye Police Department told ABC News.
