Laso was unharmed, despite claiming to have fallen off the cliff and been left unconscious for 15 minutes as a result of the incident, while his son was killed and incinerated.
Laso offered multiple versions of the events to law enforcement, and while he ultimately admitted to staging both "accidents", he never confessed to a murder.
Nonetheless, Laso also had affairs with other women including Lamas's sister Mercedes, who was herself married to Maurici Font.
At the time, Laso was sweaty, looked tired, was missing his glasses and had a scratch on the bridge of his nose, which fueled Mercedes's suspicions.
Nevertheless, Mercedes denounced the disappearances the next day after talking to a female friend and shared her suspicions about Laso.
[5] Sometime later, "Font" called the offices of the Diari de Tarragona from Morella, stating the same plus the fact that he had left in disgust after discovering that his wife was unfaithful, and requested that the investigation on their disappearance be closed.
[1][3] The Mossos searched Laso's orchard extensively, along with his bar (where he dug a hole in the basement after the disappearances) and the Amposta cemetery where he had worked as an undertaker and his first family was buried.
At Laso's home, the Mossos found Lamas's glasses, a colour copy of her DNI, the prepaid mobile phone used to call the Diari, and a crowbar and hoe that tested positive for haemoglobin.
[5] In 2010, after the disappearances but prior to his arrest, Laso had a relationship with another woman and attempted to start yet another simultaneously with a recently divorced neighbour.
[5] Laso manifested several times that he looked forward to the trial, believing that no jury could condemn him of murder without a body.
[3] Laso's murders and their investigation were the subject of the book Sin Cadáver ("Without a Body"), by Spanish journalist and criminologist Fátima Llambrich.
