Authorities say a chilling and deeply disturbing case has unfolded after a mother and her daughter-in-law allegedly conspired to kill her own son, later dismembering his body and attempting to hide the remains.

61-year-old Lorena Venier has reportedly confessed to murdering her son, 30-year-old Alessandro Venier, and dismembering him in the basement of their shared home. She claims that her daughter-in-law, 30-year-old Mailyn Castro Monsalvo, helped carry out the crime and had been involved in planning it for months.

According to police, the investigation began on July 25 when Castro Monsalvo contacted authorities to confess her role in the killing. When officers arrived at the residence — which the victim shared with his mother, wife, and infant daughter — they made a grisly discovery: Alessandro’s dismembered remains stuffed into a garbage bin in the basement.

Venier allegedly told investigators that the murder had been premeditated and motivated by a long history of alleged abuse. Both she and her daughter-in-law claimed that Alessandro had been physically violent toward them, and that they had endured years of mistreatment. She further stated that they discussed killing him for months before acting on the plan.

While the alleged motive is still under investigation, prosecutors are treating the case as a brutal and deliberate act. The confessions, along with the physical evidence found at the home, have painted a horrifying picture of family conflict turned deadly.

Neighbors have expressed shock at the events, describing the Venier family as quiet and private. “You just never think something like this could happen right next door,” one resident said.

Both Venier and Castro Monsalvo are now facing serious charges, including murder and abuse of a corpse. Authorities are continuing to gather evidence, interview witnesses, and determine whether any additional charges will be filed.

The case has sent waves of disbelief through the community — a tragic reminder of how domestic turmoil can escalate to unthinkable violence. As the legal process unfolds, questions remain about what truly led to this devastating chain of events, and whether any warning signs could have prevented it.
