To my team, thanks. pleasehelpfinddaniel.com https://t.co/5mSZLZfffdThere was a dispute over whether foul play was involved in Daniel Robinson's disappearance. Police authorities believed that there was nothing at the site to indicate that the disappearance was at the hands of another individual. A statement regarding the case made by the authorities, read:"When a loved one is missing, it is a terrifying, confusing and stressful time for families and our entire community. Investigators continue their pursuit of answers that can bring Daniel home and provide closure for the Robinson family and the many people who have been touched by his case."On the other hand, Daniel’s father and a private investigator named Jeff McGrath, who specializes in accident reconstruction, believed something else. According to Jeff, this was the most mysterious case he had ever worked on and he believed that the vehicle’s airbags had been deployed at another location before it was driven to the ravine.4) Questions arose over Daniel's mental statePlease Help Find Daniel@PleaseHelpFind4I love the A-Team!!

Police reports said that no second person was involved in the case and also dug into Daniel’s mental state before he went missing. It was revealed that Daniel had a fixation on a woman named Katelyn, to whom he delivered groceries.Although Katelyn told the police she had no relationship with Daniel, another friend of his mentioned that Daniel had reportedly hooked up with one of the girls he delivered to. Katelyn told the police that Daniel became obsessed with her and started showing up at her house and texting her about how much he loved her. When Katelyn asked him to stop, he texted:“The world can get better, but I’ll have to take all the time I can or we can, whatever to name it. I’ll either see you again or never see you again.”The picture of Daniel Robinson as a scorned and depressed man did not fit with his father's version of him. He believed that his son was a go-getter, a scientist, who had the potential to change the world because a bright future lay ahead of him.5) Daniel's dad David Robinson took matters into his own handsPlease Help Find Daniel@PleaseHelpFind4Good morning.

Jeff is a former cop and vehicular crime investigator. Most of the searches for Daniel Robinson were conducted by volunteers, groups, and Robinson's family. David, who was fed up with the Buckeye Police and their meager attempts to solve the case, said:"So far, I have conducted over 40 weeks of searches in the Sonoran Desert, a search based on science and investigation that covers large amounts of land. We have searched over 23K acres of that large area that has areas that haven't been searched yet. I am currently working on that."6) David Robinson still holds out hopePlease Help Find Daniel@PleaseHelpFind4Imagine if this picture is the only thing that you have to while seeking answers to why your son is missing.
