Last Friday, Andreu Coll junior, along with his accomplice and friend Francisco Abas Rodriguez, owned up to the killing of millionaire businessman Andreu Coll senior.
The murder took place on the night of the 29th of June in the small Majorcan municipality of Alaró, Spanish newspaper El Mundo reported recently.
The pair admitted to having first drugged Andreu's father before bludgeoning him with a medieval-style spiked bat, a vase, a hammer and a music speaker.
After cleaning up the blood and fingerprints with bleach, Coll and Abbas drove in the victim's Land Rover to the nearby town of Bunyola.
Their intention was to make it look like a robbery and so removed Coll senior’s Rolex and rings before dumping the body.
Although the pair went to the victim's funeral, Spain’s Civil Guard soon arrested them after infrared tests showed them to be the real murderers.
Coll and Abbas first met online a year and a half earlier while playing the popular videogame Call of Duty.

According to Abas's lawyer, his client fell in love with Coll after the pair spent time together in Majorca and Zaragoza.
Both young men were obsessed with violent video games, spending up to 12 hours at a stretch in front of their screens.
Police believe the medieval-style spiked bat they manufactured was based on a similar weapon found in Dead Rising 2.
Coll told a Majorcan judge he'd decided to murder his father because of constant humiliation on the victim's part.
But he is also heir to a €50 million fortune, a fact Spanish media have taken to indicated their money may have also been a motivation for the murder.
Abas's lawyer told the court that his client "regretted taking part in the murder but had done it for love".
The Regional High Court in the Balearic Islands has dictated a nondisclosure order while the trial continues.
