Swords murder conviction under appeal over Tinder evidence

Marius Mamaliga, a 19-year-old man, was stabbed once in the neck with a knife while sitting in his car at Forest Court, Swords, on the evening of 23 February 2023, and died in Beaumont Hospital three days later. Brandon Gavin, a man from Swords, handed himself in to gardaí about an hour and 20 minutes after the incident and was charged with murder on the DPP's direction after an initial charge of causing serious harm. Gavin, aged 20 at the time of the incident and 22 at his conviction, pleaded not guilty claiming self-defence over a drug debt, but a Central Criminal Court jury unanimously convicted him in November 2024 and he was sentenced to life in prison in December 2024. Gavin is now appealing, with the Court of Criminal Appeal reserving judgment in February 2026 on the admissibility of Tinder and text message evidence.

What happened
Marius Mamaliga, a 19-year-old man, was stabbed once in the neck with a knife while sitting in his car with two friends at Forest Court, Swords, on the evening of 23 February 2023.
Where
The stabbing occurred at Forest Court, Swords, Dublin; some reports identify the location as Brookdale Avenue, Swords.
When
Gardaí responded to the assault at approximately 7.14pm on 23 February 2023; Mamaliga was pronounced dead at Beaumont Hospital on 26 February 2023.
Cause
Mamaliga died from hypoxic brain injury caused by blood loss, with arterial bleeding to the left common carotid artery, damage to the left jugular vein and upper windpipe.
Weapon
A knife was used; a penknife with the victim's blood was found in a park nearby and the handle contained DNA matching Gavin.
Investigation
Gavin handed himself in to Swords Garda station about an hour and 20 minutes after the incident after his father brought him there; his mobile phone and two HSE appointment cards were recovered from the car footwell.
Charges
Gavin was initially charged under section 4 of the Non-Fatal Offences Against the Person Act with causing serious harm, then further charged with murder on the DPP's direction, with the earlier charge withdrawn.
In court
  • Gavin pleaded not guilty; a Central Criminal Court jury of seven men and five women unanimously convicted him in November 2024 after deliberating for close to five hours, rejecting his self-defence claim.
  • Gavin is appealing his conviction at the Court of Criminal Appeal, challenging the admissibility of Tinder and text message evidence; the three-judge panel reserved judgment in February 2026.
Sentence
Gavin was sentenced to the mandatory term of life imprisonment by Ms Justice Eileen Creedon in December 2024.
Other details
  • Gavin claimed self-defence, saying he feared for his life because he owed Mamaliga a drug debt of between €2,000 and €2,500.
  • Gavin's phone was used to search for 'prison sentence for murder in Ireland' on 22 February 2023 and was active on the dating app Tinder about 20 minutes before the stabbing.
