Leandro Acosta, 25, of Argentina, confessed to police officials that he murdered his 50-year-old mother Miryam Kowalczuk, and his step-father, Ricardo Klein, in their Pilar home just before having sexual intercourse with their dead bodies and eating some of their remains, according to the Daily Mail.

Sources say that the couple abused Acosta and his 22-year-old step-sister Karen Klein, who reportedly began dating three years ago after she and her father moved into his home, when they were younger. It is unclear if police officials were notified of the child abuse, but when Acosta learned that his 11-year-old twin sister and brother were being abused by their parents, he immediately alerted the police.

However, when the Argentina police didn’t react quickly enough, he took matters into his own hands. He waited until his siblings left for school and went into his parents’ bedroom where his step-father was sound asleep and shot him dead. He murdered his mother as well by a single gunshot wound to the head as she was entering the bedroom.

According to the Express, after Acosta killed his parents, he had sexual intercourse with their dead bodies before eating some of their remains. With the help of his step-sister, he chopped up the bodies and fed it to their six dogs. Parts of the body that were not given to the dogs were burned and stashed away in their home.

After learning of Ricardo’s death, his brother Roberto Klein commented on the allegations.

“My brother was a difficult man, with little time for his children, there has always been resentment between him and his stepson and I believe this was a long time coming.”

It is believed that Acosta not only killed his mother and step-father for abusing his 11-year-old twin siblings as well as himself and his step-sister, but for being ridiculed and mistreated throughout his life for having a chronic intestinal illness that caused him to use colostomy bag, reported the Independent.

Acosta’s attorney, Monica Chirivin, claims that as a result of his abusive past, “he does not feel remorse and in fact describes a state of relief for a burden he has felt since childhood.” Acosta also confessed to his attorney that he ate some of his parents’ remains after killing them and claims that the feeling was “almost a pleasure.”

A family member – whose name has not been released – stated that they began to worry when they hadn’t seen the couple since September of this year. They tried desperately to get in contact with Kowalczuk and her boyfriend but were unsuccessful and that’s when they decided to stop by their home. The relative became suspicious when Acosta wouldn’t allow them to enter the home, so they immediately alerted Argentina police. The home was searched and not only did the police discover a female pelvic bone but they also found a “vertebra column in an old paint bucket on the terrace.”

Acosta and his step-sister were both taken into custody for questioning, but the interrogation didn’t last very long as Acosta confessed to murdering his parents, having sex with their dead bodies, and eating some of their remains before feeding them to their dogs. Karen was also taken to the police station and claimed that she had no part in the killings of her parents or cannibalizing them. She was only following her step-brother’s orders by helping him dispose of their bodies by chopping them up and burning them so that their bodies would never been found.

An investigation is underway and the crime squad plans to analyze a waste ground that’s near their home after learning Acosta and his step-sister dumped a suspicious bag. However, both Leandro Acosta and Karen Klein remain in police custody and could face first-degree murder charges.
