Pic shows: Franco Rodrigo Gaspar Cinco, convicted of the murder of his girlfriend and her son. A 28-year-old journalist has been sentenced to life in prison for giving his girlfriend and her toddler son cyanide disguised as holy water and killing them both. Franco Rodrigo Gaspar Cinco from Salta Province in north-west Argentina was convicted of murdering his partner Alejandra Parraga, 26, and her two-year-old son Amir Parraga. According to reports, Gaspar Cinco killed the pair in June 2017 when he visited his girlfriend’s home carrying a bottle of holy water that he said would help with the tot’s sickness. As soon as he drank some, the toddler collapsed. His mother instantly tried to perform mouth-to-mouth resuscitation on her two-year-old, but came into direct contact with the poisonous chemical compound. The young boy’s grandparents rushed him to hospital but he died shortly after being admitted. His mother perished before arriving at the Hospital San Bernardo. Gaspar Cinco was arrested the next day during the victims' funeral. Before the boy’s death, prosecutors said that the 28-year-old journalist allegedly tried to get rid of his girlfriend’s son in other ways because the youngster’s presence bothered him. Throughout the trial, the suspect maintained his innocence. In court, Gaspar Cinco said: "I never intended to end Alejandra’s life nor her son’s. I had plans with Alejandra, she was the love of my life. "I have a four-year-old son. So, as a parent, how do you think that I could do that to somebody else? "I cannot control what has happened to me, but I did not have the intention or ability to carry out what has been assumed." (ends)
