However, after not being seen for a fortnight at the beginning of the year, he was reported missing to local authorities.
Despite renewed attempts to locate him, the search has hit a brick wall.
And following legal advice in the US, his family have now set a target of £20,000 to appoint expert hired help to try to shed some light.
"Bryn left the UK and rugby league 10 years ago to go to the USA," said Bryn's brother, Gareth.
"He has had some unfortunate life events and became isolated due to Covid, leading to mental health issues of late.
"We appreciate all the hard work of the local/state police departments and helpful community, but unfortunately, after five months, there have been no leads or progress.
"My mum and brother flew out to the USA on January 28 for seven weeks, thanks to the support of Rugby League Cares, for which we will be eternally grateful.
"Despite gathering further information and investigating many avenues, there are still no leads or progress.
"We are no closer to finding Bryn after five months and fear for his welfare
"We would now like to appoint a private investigator, following legal advice from a former assistant district attorney in the USA.
"Our goal is to raise £20,000 to fund private investigators to look into Bryn's disappearance.
"All monies donated will principally be used to fund the investigation into Bryn's disappearance.
"The fund balance may be used in repatriation if the worst is found.
"Some monies may need to be used for legal expenses in sorting and protecting Bryn’s assets, with my mum potentially needing to go back over to the USA to do so.
"Any remaining balance will be donated to Rugby League Cares to continue their great work in the aftercare of players and generally within the rugby league community."
