In a case that has highlighted the dangers of social media grooming and the vulnerabilities of young children online in the Cayman Islands, George Martin Slijper was sentenced today, February 10, 2026, to a total of 14 years in prison for a series of sexual offenses against three girls aged between 11 and 13.  The offences included sexual communication with a child, meeting a child following sexual grooming, assault by penetration, gross indecency and rape. The offences followed contact on Snapchat and Instagram.

Regarding the first indictment (number 106/23), Slijper initiated contact with a 13-year-old girl on Snapchat.

After having exchanges of a sexual nature via social media, including nude photos and videos, Slijper met the young girl in a public bathroom at a hotel where he had intercourse with her.

Reportedly, the young girl’s mother became suspicious of her daughter’s movements at the hotel and questioned her daughter. The young girl later admitted to being with Slijper. 

It is understood that Slijper initially denied the allegations, but was later found guilty in May 2024 of sexual communication with a child, meeting a child following sexual communication, assault by penetration, gross indecency, and rape.

Regarding the sentences for these offences, Justice Carter determined the following:

Offence	Starting Point	Actual Sentence
Count 1 (Sexual Communication)	4 years	3 years
Count 2 (Meeting Child)	4 years	3 years
Count 3 (Assault by Penetration)	18 months	12 months
Count 4 (Gross Indecency)	3 years	2 years
Count 5 (Rape)	10 years	8 years

The above sentences for indictment number 106/23 will run concurrently, resulting in an effective 8-year term.

Concerning the second indictment (number 27/24), Slijper contacted two girls.

Slijper communicated with the first girl on Snapchat, adding her as a contact in January, 2023 when she was 13-years-old.

Reportedly, they continued to message each other on Snapchat and Instagram, after which Slijper picked her up in his car and had sexual intercourse with her on several occasions.

Regarding the second girl related to indictment number 27/24, Slijper contacted her on Instagram when she was between and 11 and 12 years old.

It was explained in court that the young girl initially ignored Slijper, but he persisted.

At some stage, there was conversation about the girl, her cousin and Slijper having a threesome.  However, there was no sexual activity between them.

Regarding the sentences for these offences under the second indictment number 27/24, Justice Carter determined the following:

Offence	Starting Point	Actual Sentence
Count 1 (Sexual Communication with first child)	24 months	15 months
Count 5 (Assault by Penetration)	18  months	15 months
Count 7 (Rape)	10 years	8 years, reduced to 6 years
Count 10 (Possession of Indecent Images)	8 years	6 years
Count 12 (Sexual Communication with second girl)	18 months	12 months

These sentences for indictment 27/24 will run concurrently, yielding an effective 6-year term.

Adding the sentences from the two indictments means Slijper will serve 14 years, with deductions for time already spent in custody.

In delivering the sentences, Justice Carter applied Cayman Islands Sentencing Guidelines, balancing aggravating and mitigating factors. Aggravating elements included the victims’ young ages (11-13), the grooming via social media, and the involvement of multiple complainants.

Mitigating factors encompassed Slijper’s lack of prior convictions, expressions of remorse, and significant mental health issues, including bipolar disorder, generalized anxiety disorder, post-traumatic stress disorder, attention deficit hyperactivity disorder, and a learning disability that placed his mental age at around 15-years-old.

Additionally, the court imposed a Sexual Harm Prevention Order, lasting 10 years from Slijper’s prison release date. While the details were not shared in court, it is understood that the order prohibits certain behaviours to protect the public, with violations punishable by up to 4 years’ imprisonment.

Justice Carter recommended that Slijper participate in rehabilitative programs for sexual offenders and mental health treatment while incarcerated, noting the absence of a secure psychiatric facility in the Cayman Islands.

Note to readers

It is noted that victim impact statements were limited in these cases, as the young girls expressed a desire to move on. Two of the girls declined full participation, but reports indicated ongoing emotional trauma, including anxiety attacks and family distress.

Slijper’s sentences today should spark discussions in the Cayman Islands about online safety for children and the need for enhanced mental health resources, including a secure psychiatric facility.
