Ex-NFL player's son remains 'missing and endangered' after two weeks as Indiana police reveal allegations of abuse against 'uncooperative' parents

Indiana police have issued a Silver Alert for a former NFL player's missing son, who is believed to be in extreme danger amid allegations of abuse against the parents.

Byrson Muir, the 14-year-old son of retired Indianapolis Colts defensive tackle Daniel Muir, was last seen leaving a family member's home in Ohio two weeks ago, according to Indiana State Police, who now say parents Daniel and Kristen have become uncooperative.

'Earlier today, Daniel and Kristen Muir had agreed to bring their 14-year-old son Bryson to meet with ISP investigators at the Peru Post,' Indiana State Police explained in a press release. 

'The agreement was to meet at 12:00 p.m. At approximately 11:00 a.m., the Muirs backed out of that arrangement which signaled an unwillingness to cooperate.'

Police cautioned that the investigation is still ongoing and urges anyone with information to call the Peru Post at 1-800-382-0689.

Described as a 6-foot-2, 185-pound black mail with black hair and brown eyes, Bryson was last seen with a bruise around his eye, as pictured in a photograph shared by police. The child's grandmother recently reported that black eye to police and told officers her grandson could be the victim of abuse at the hands of his parents.

According to police, Bryson was seen leaving a family member's home in the Cleveland suburbs on June 16 in his mother Kirsten's white 2015 Chevrolet Suburban. The car, which Kirsten was said to be driving, belongs to a Kokomo, Indiana organization known as the Servant Leader's Foundation.

However, when that vehicle was pulled over by police in Garfield Heights shortly after leaving the residence, Bryson was no longer in the vehicle. Police remain puzzled at how Bryson went missing in the short time between being picked up by his mother and her being pulled over by local police.

'It was minutes, it wasn't a very long period of time whatsoever,' Indiana State Police Captain Ron Galaviz said, as quoted by Indianapolis' Fox 59. 'But in that period of time, Bryson wasn't able to be found. We don't know where he went.' 

Two days later, the Cass County Department of Child Services called Indiana State Police to investigate accusations of domestic battery against Bryson at the Muir family home in Logansport, Indiana.

Like the car, that property is owned by the Servant Leader's Foundation, according to Indiana State Police.

DailyMail.com's efforts to contact the Muir family and the Servant Leader's Foundation have been unsuccessful.

The 40-year-old Daniel is a Washington DC native who played at Kent State before going undrafted in 2007. Ultimately he signed with the Green Bay Packers before spending three seasons with the Colts and parts of the 2012 campaign with the New York Jets.

Daniel has also worked as the Indianapolis chapter pastor for Straitway Truth Ministries, who describe themselves as 'nation of Hebrew Israelites.' 

Former Packers star Kabeer Gbaja-Biamila also joined that ministry after denouncing Christianity, according to SI.com. 

Another former Colts player, Robert Mathis, has been linked to the organization, which has been described the Southern Poverty Law Center as a potential hate group over anti-LGBTQ and anti-Semitic ideology.
