Waukegan Police are asking for help to find the missing Seamus Gray, a 21-year-old member of the United States Navy who has disappeared without a trace since Saturday morning.

Seamus was reportedly at Naval Station Great Lakes on Friday night before heading to Waukegan to join the St. Patrick’s Day celebrations – but was never heard from again after that.

If anyone has seen or heard recent information about his disappearance, they are encouraged to contact local law enforcement as soon as possible.

Detectives have uncovered crucial video evidence showing Gray leaving the Ibiza Bar in Waukegan alone. He was last seen at 1:40 a.m. Saturday at the intersection of Sheridan Road and Washington Street.

As a result, Waukegan police and firefighters have thoroughly searched the area around Ibiza Bar and the lakeshore, but have still not been able to find Gray.

After talking to Gray’s mother, who came to Waukegan from out of town to help find her son, CBS 2’s Jermont Terry reported seeing the bar’s surveillance footage.

For now, detectives are only considering this a missing persons case.

Gray’s story has become increasingly worrisome due to additional video of an altercation involving her son and a group of people.

The incident was captured by security cameras and Gray has yet to be located since his disappearance last Thursday.

His family continues the frantic search for him, carefully combing the area in hopes of finding him or any clues that could lead to his whereabouts.

With no news from his naval base, Gray’s mother fears the worst as each day passes with no trace of her beloved son.

A manhunt is underway for Gray, who is wanted in multiple states, and his mother has said the Naval Criminal Investigative Service (NCIS) is also involved in the case.

He stands at 6-foot-3 and weighs about 170 pounds; he has blue eyes, brown hair and multiple tattoos on his left arm, with a written tattoo on his ribcage.

On the day of his disappearance, he was last seen wearing a pale pink or red long-sleeved shirt paired with trousers.

Any relevant details or information should be reported to the Waukegan Police Department using their official app.

Any tips are appreciated and will help police officers move Gray closer to finding it.
