Suspect Named in Random Fatal Stabbing of Elderly Woman in Martin County Neighborhood

A 25-year-old man with no known criminal history attacked and killed an elderly woman walking her dog in a quiet Martin County neighborhood Thursday, in what the sheriff's office is calling a random, unprovoked act of violence.

Kersten Francilus has been charged with second-degree murder in the death of a woman in her 70s who was stabbed multiple times on the 6000 block of SE Black Oak Lane in the Southwood community. The victim's name has not been released by the Martin County Sheriff's Office as of Friday morning. Officials said

Sheriff John Budensiek said the victim sustained a "significant amount of stab wounds to the upper torso" from a steak knife. She died at the scene or shortly after. Officials said

Francilus was still stabbing the woman when a male neighbor — who asked not to be identified — rushed over after hearing screams. The neighbor told WPTV he had spoken with Francilus just moments before the attack and noticed something was off.

"He wasn't all there," the neighbor said, adding that Francilus was nonetheless speaking coherently at the time. When the neighbor tried to physically pull Francilus away from the victim, he said Francilus was too heavy and appeared oblivious. Francilus stopped only when deputies arrived and ordered him to the ground at gunpoint.

Prior to the attack, Francilus had been knocking on doors in the neighborhood and asking residents where a nearby bank was located. Budensiek confirmed there is no bank in the area. Deputies had been dispatched after neighbors reported a man at their doors behaving erratically — a call that puts the timeline of police response in close proximity to the stabbing itself.

Investigators have found no known connection between Francilus and the victim. The sheriff's office confirmed Francilus has no prior criminal record, but acknowledged one prior call to service at his residence. In that earlier incident, family members had contacted authorities reporting that Francilus was "acting erratically." No charges resulted from that call. Officials said

"So we don't know of any motive," Budensiek said. "We just simply know that we've had a horrendous crime that's taken place in this neighborhood."

A second neighbor described the victim as a familiar presence in Southwood, identifiable even in her final moments by the shoes she regularly wore on her walks. That neighbor said the woman's husband had died 10 to 15 years ago.

The investigation remains active. Prosecutors will determine whether charges will be elevated. Officials said
