Son Stabs Mother Over 40 Times Because She Was Mean to Him Growing Up

A Last Meal Before Murder

A son Derek Rosa faces a charge of first-degree murder and is currently in a county jail awaiting trial, where he will be tried as an adult.

He had one final meal at Dairy Queen before going home and stabbing his mother over 40 times in the back and neck. His reason? She was "mean to him" growing up. That is what he told police after they found her body.

Over 40 stab wounds. In the back and neck. Inflicted by her own child. The level of rage required to do that to another human being, let alone your own mother, is almost incomprehensible. And he sat down for ice cream first.

The Calm Before the Storm

What makes this case especially chilling is the premeditation. This was not a sudden outburst during an argument. He went to Dairy Queen, ate a meal, and then returned home to commit murder. That gap between the decision and the act shows a cold, calculated mindset that investigators say points to first-degree murder.

Witnesses at the restaurant reported nothing unusual about his behavior. He ordered food, ate it, and left. Nobody had any idea what he was about to do.

Years of Resentment

According to police, the suspect told investigators that his mother had been "mean to him" throughout his childhood. Whether that means verbal abuse, physical abuse, or simply strict parenting that he resented, authorities have not clarified. But nothing justifies what he did.

If he was genuinely abused as a child, there are resources, therapists, and legal avenues to address that trauma. Stabbing your mother 40 times is not justice. It is murder.

Facing Life in Prison

The suspect is in custody and facing first-degree murder charges. Given the number of stab wounds and the evidence of premeditation, prosecutors are expected to push for the maximum sentence. A conviction would mean life in prison without the possibility of parole in most jurisdictions.

His mother cannot speak for herself anymore. But the evidence speaks volumes. Rest in peace to a woman whose own son became her killer.
