ORLANDO, Fla. — A federal judge in Orlando is expected to decide Friday whether to release a Full Sail University student accused of hitting an officer in the head with skateboard during the January attack on the U.S. Capitol.

Federal prosecutors want to jail Grady Douglas Owens, 21, of Winter Park until his trial on three felonies and one misdemeanor stemming from the January 6 invasion in Washington, D.C.

Owens, a musician with long black hair from Blanco, Texas, appeared before U.S. Magistrate Judge Daniel Irick during an 8-minute hearing Thursday at the George C. Young Federal Courthouse Annex.

He is being held overnight in an unspecified jail and is scheduled to return to court for a detention hearing at 10 a.m. Friday.

His criminal complaint was filed in the District of Columbia on Thursday, the day of his arrest.

Federal prosecutors released details of the allegations after Thursday's hearing.

Owens wielded a WhiteFang brand skateboard, according to federal records.

Assistant U.S. Attorney Karen L. Gable told Irick federal prosecutors are seeking pretrial detention for Owens because of his alleged “crime of violence.”

Gable said the defendant’s most serious charge — assaulting, resisting, or impeding certain officers or employees with a deadly or dangerous weapon — carries a maximum penalty of 20 years in federal prison.

He also charged with knowingly entering or remaining in any restricted building or grounds without lawful authority, a crime punishable by up to 10 years behind bars.

A third felony, obstruction of law enforcement during civil disorder, carries a punishment of five years in prison.

The misdemeanor charge of violent entry and disorderly conduct on Capitol grounds is punishable by up to a year imprisonment.

Officer Christopher Boyle of the Metropolitan Police Department's Fourth District suffered a concussion in the skateboard attack at 2 p.m. January 6, records say.

At the time, Boyle and roughly 33 other officers were walking through the west lawn of the Capitol grounds, responding to calls for assistance because of the ongoing riot at the Capitol building.

An image from another officer's body-worn camera of the suspected attacker was made public.

"The unknown subject is listed in the FBI Wanted Poster as Subject 109," the report said.

An agent spotted the wanted poster and other images of the same person on a Twitter account called @SeditionHunters, which is run by a person who is helping officials identify Capitol attack suspects.

An online search of a clearer picture of the suspect from Sedition Hunters led investigators to an Instagram profile for Grady Owens and a photo of the suspect wearing a stocking cap. 

It appeared to be the same cap worn by Subject 109.

Agents linked him to vehicles registered in Texas and spotted in an apartment complex and Full Sail University, both in Winter Park. The university offers music and recording degree programs.

An unnamed Full Sail employee identified Owens as the person on the Instagram account and in a YouTube video. 

In a written response to a Spectrum News inquiry into his status as a student, Full Sail University said late Thursday night that "it has been brought to our attention that someone who has been potentially identified as a current student has been arrested in connection with the riots at the Capitol that occurred earlier this year. The university plans to closely monitor the judicial process and will respond accordingly, and in alignment with the university’s policies. Full Sail University does not tolerate or condone acts of violence at any time."

Agents say Owens and another person with the same last name flew from San Antonio, Texas to Dulles International Airport outside of Washington, D.C. on January 5, the day before the attack. 

The report does not explain their relationship.

They flew from Reagan National Airport, also near D.C., to San Antonio the day after the attack, the report noted.

San Antonio is about 25 miles from the defendant’s hometown of Blanco.

On the Bandmix website, a person who looks like Owens and uses the screen name gradyowens describes himself as a “super dedicated” musician  from Blanco whose main influences “are U2, Coldplay, Switchfoot…”

A Facebook page called Grady Owens describes the user as “a small musician in a big world.”

On Thursday, Owens said little beyond answering the judge’s questions. Irick asked whether he had a private attorney.

“I think my parents are getting me one,” Owens responded.

His parents were not in the courtroom. Neither was a private attorney. So Irick appointed a public defender for Owens, saying a private attorney can step in later.

Owens wore a black T-shirt with a Vans logo, brown shorts, and loosely tied sneakers.

He joins a growing number of suspects linked to Central Florida in the January 6 siege of the U.S. Capitol.

In all, more than 300 people, many supporters of former President Donald Trump, from across the country have been charged in the attack.

Invaders falsely alleged Trump, a Republican, lost the November 3 general election and attempted to block Democrat Joe Biden's Electoral College victory in the U.S. Capitol.

Suspects from Central Florida include alleged members of a white supremacist group called the Proud Boys, self-described “Western chauvinists.”

On Tuesday, Arthur Jackman, 30, of Orange County wore a Proud Boys T-shirt when he appeared before Irick for the first time on a criminal complaint filed by D.C. federal prosecutors. He was released on a $25,000 unsecured bond and a promise to follow a laundry list of conditions of release.

Agents said Jackman was spotted with Joseph Randall Biggs of Ormond Beach, another accused member of the Proud Boys, before and during the Capitol attack.

Other accused attackers from Central Florida are suspected members of the far-right, paramilitary-style organization called the Oath Keepers.

Kelly Meggs of Dunnellon in Marion County is an accused Florida leader of the Oath Keepers. He and wife Connie were charged in February with plotting with other suspected Oath Keepers to infiltrate the U.S. Capitol.

Federal prosecutors allege Oath Keepers shouldered their way into the building and used two-way communication devices while inside.
