The young man with train-track braces and an awkward teenage grin, Tyler Robinson, was seen as nothing less than ‘handsome’ and ‘wonderful’ by his mother and grandmother.

Amber Robinson, who worked with disabled children, and her mother-in-law, Debbie, shared numerous photos of the young man they adored, along with his two younger siblings.

Now, this formerly awkward teenager is accused by US officials of being a hate-filled extremist, recently becoming America’s most wanted individual, with President Donald Trump calling for his execution.

Robinson allegedly transformed from a politically curious son residing in a $600,000 six-bedroom home in Washington, Utah, into one of the most infamous figures in US history, as per US officials. This home is about 260 miles south of where Charlie Kirk was murdered.

According to officials last night, Robinson had allegedly said during a recent dinner that ‘Charlie Kirk was full of hate and spreading hate’.

Neighbor Kristin Schwiermann, 66, expressed her shock, describing him as ‘very respectful and quiet’ with friends, emphasizing that he came from a ‘very loving family.’

‘I love his mother, and he’s from a hard-working family.’

The Robinson family’s Facebook profiles are filled with happy, everyday snapshots. Among them is a 2018 photo on Robinson’s mother’s Facebook, showing them both posing for a portrait when he was 15. 

Last night, someone has added the comment: ‘Murderer! Your life is over. Judgment day is coming.’ 

Alongside one photo of three brothers posing by a waterfall, their grandmother Debbie Robinson wrote: ‘How lucky I am to have such handsome grandsons.’

Yet in the hours since Robinson was arrested by the FBI, outraged members of the public have been able to add a stream of comments to the family album, such as, ‘Learn how to parent and maybe your son wouldn’t have done that!’

On one picture of teenager Robinson next to the Grand Canyon, a Facebook user named Travis has added the comment: ‘Shoulda jumped’.

And to a camping photo of Tyler with a dog, snapped in 2018, someone has now written: ‘Poor dog, no idea he has a maniac standing behind him.’

Robinson was taken into custody on Thursday night in southern Utah after having allegedly confessed to his father, who persuaded him to turn himself in with the help of a local youth pastor.

Tyler’s father recognised him from images released by authorities and encouraged him to turn himself in, a law enforcement official revealed.

Alongside the ‘happy family’ snaps, there are plenty that reveal his love of high-powered machine guns. In one image from when Robinson appeared to be a teenager, he was seen posing with an M2 Browning .50-calibre machine gun, another showed him posing with a scoped rifle. In another, he was holding a bazooka.

Facebook posts from his mother showed Robinson and his two younger brothers at gun ranges and military events. In one post, Amber was seen holding a US army machine gun.

One picture of the son whom Amber called her ‘man child’, showed them dropping him off at university – apparently wearing the same trainers as in the FBI ‘wanted’ pictures.

He attended Utah State University for one semester in 2021, according to a university spokesman, before dropping out and moving back home to complete an electrical apprenticeship programme at Dixie Technical College.

His mother wrote she was hoping ‘he’ll pick a Utah college and stay close to mamma’, adding: ‘His options are endless!’

Last night Mr Trump said: ‘I hope he’s going to be found guilty, and I hope he gets the death penalty.’
