An Alabama mother-son duo were kicked off a cruise ship after they were allegedly caught on video committing a vile act against a senior citizen passenger. 

Kelli Lyn Ryan, 49, and her son, Dylan Ryan, 23, of Huntsville, were accused of ‘open-hand’ slapping another passenger said to be over the age of 65 on the MSC Seascape cruise out of Miami, Florida, which had 6,000 passengers onboard. 

Surveillance footage obtained by police allegedly showed Kelli slap the victim, whose identity remains unknown, inside the ship’s two-deck theater after an argument broke out around 9:30pm on October 6.

Her son was also seen in the video striking the much older victim several times, the ship’s deputy chief of security told police, according to Local10.

Dylan was ejected from the nearly 6,000 passenger boat for ‘excessive behavior’ after the cruise stopped at its first port in Falmouth, Jamaica, police reports reveal

Police said Dylan was kicked off the ship the following day for his part in the altercation when the cruised docked n Falmouth, Jamaica, for ‘excessive behavior’. 

But the 23-year-old’s mother was permitted to stay on the ship as it made stops in the Grand Cayman Island, Mexico and MSC Ocean Cay, which is the cruise ship company’s private island in the Bahamas.

Nearly a week later, when the Seascape returned to Miami, Kelli was arrested and charged with battery on a person 65 or older.

However, the 49-year-old no longer appears to be in jail and her whereabouts is unknown, Local10 reported.

Further details of the  altercation have yet to be released. 

MSC Cruises have not publicly released a statement about the incident either. 

Onlookers have taken to social media in the days after the incident to speculate what may have happened to the 23-year-old who was left in Jamaica, as well as why his mother may have stayed on without her son.

‘Wow, how ‘excessively’ violent do you have to act for MSC security actually kick you off the cruise ship in a foreign port?’ Cruise Law News on Facebook posted. 

‘Being dumped in Jamaica with no resources is no joke either,’ another user added.

With another replying: ‘Cruising on these big ships is dangerous, on so many levels.’ 

Passengers being removed from cruise ships is relatively rare, only occurring when there are severe behavioral issues or serious medical conditions.
