HOUSTON – A lawyer for the family of John Hernandez has released a new witness video in connection with the fatal beating of the 24-year-old outside a Denny’s restaurant.

Attorney Jack Carroll released the video Monday during a press conference.

"An anonymous concerned citizen brought me the video because he said it shows murder," Carroll said. "I concur."

The video can be seen below.

WARNING: The video contains graphic and violent images.

WATCH: New video released connection with fatal beating

The man who beat Hernandez saw him urinating outside the restaurant, according to the Harris County Sheriff's Office.

Witnesses say Hernandez was quickly overpowered by the man, who continued to beat him then put him in a chokehold for 10 to 15 minutes. They said Hernandez, who was much smaller, than the man, was too drunk to defend himself.

“It’s a very sad video because you’re watching a man basically being killed,” Carroll said. “He was kicking his legs in a helpless fashion, and you can hear him gargling or gurling, ‘Stop, stop.’”

Hernandez's wife and 3-year-old daughter were begging the man to stop.

“She was crying and telling (the man beating Hernandez) stop and he didn’t even stop,” Hernandez’s wife said. “I told him, 'Please stop. Don’t do that to him. He’s drunk.' He wasn’t in any position to fight. But, he didn’t have any compassion. He was really angry.”

The other man involved in the incident is the husband of a Harris County Sheriff’s Deputy and has not been arrested or named as a suspect.

His wife, the HCSO deputy, was also present during the incident.

Harris County Sheriff Ed Gonzalez says the deputy helped to restrain Hernandez but then called for help when she noticed he was not breathing.

Eyewitnesses say the deputy did nothing to help and stood by while her husband continued to beat and strangle Hernandez.

“The husband of the off-duty sheriff has the man in what you would call a ‘reverse headlock,’ for lack of a better term,” Carroll said. And he has the man helpless. The husband of the off-duty sheriff’s deputy looks like he weighs at least 300 pounds. Extremely big. He’s very muscular.”

Hernandez was removed from life support three days after the incident.

The video may not be enough evidence to file criminal charges, according to KHOU 11 News legal analyst Gerald Treece.

He viewed every angle of publicly released surveillance video captured inside the Denny's on Crosby Freeway in east Harris County.

It first showed Hernandez push past his wife to urinate outside. There, Hernandez ran into the husband of a Harris County Sheriff’s deputy. He confronted Hernandez, then “restrained him" investigators said.

“The guy on the bottom really is not resisting/ is he?" Treece asked while watching the videos. "He can’t. That guy (on top) is too big.”

While lawyers for the witness who shot the cell phone video release Monday and Hernandez’s family see a crime.

Treece needs to see more.

“The film, while it’s very interesting, it doesn’t answer the questions a grand jury is going to have to answer," Treece said.

Texas law only allows citizens to use deadly force when facing an imminent threat to their lives, Treece said. In the Hernandez case, that threat is hard to see.

“If so, when did that imminent fear occur?" Treece asked. "Did it ever stop?”

Grand jurors will likely see complete unedited clips of the scuffle, Treece said. However, how they rule is always a question of who and what grand juries believe, he added.

Sheriff Gonzalez said the homicide is still under investigation and stated he is asking for oversight of the HCSO investigation by the Texas Rangers and the U.S. Department of Justice.
