MOUNDSVILLE, W.Va. - Three people are dead after a double homicide and a fatal deputy-involved shooting at a home near Moundsville early Thursday morning, according to the Marshall County Sheriff's Office.

Sheriff Mike Dougherty identified the two people found dead inside the home as David D. Will, 44, and his wife, Monica L. Will, 46.

Both had suffered gunshot wounds.

The sheriff identified the suspected gunman as 25-year-old Cyle B. Fabrizio of Moundsville.

Fabrizio was fatally shot by a Marshall County deputy after authorities say he fired at responding officers and then held the Wills' 16-year-old daughter at gunpoint.

The Marshall County Sheriff's Office and West Virginia State Police are jointly investigating both the homicides and the deputy-involved shooting.

Silent 911 call prompted response

The incident began at approximately 1:40 a.m. Thursday when Marshall County 911 received a call from a residence on Middle Grave Creek Road.

No one spoke on the other end of the call.

Deputies were sent to the residence to investigate.

As they approached the home, Fabrizio allegedly fired a pistol at them, according to Dougherty.

The deputies took cover and began trying to determine where the gunfire was coming from.

Authorities then saw Fabrizio in the doorway with a juvenile girl.

Sheriff says teen was held at gunpoint

Dougherty said Fabrizio was holding the 16-year-old girl around the neck with a pistol pointed at her head.

A deputy armed with a rifle determined the teenager was in immediate danger and fired one round at Fabrizio, according to the sheriff.

Fabrizio was struck and died from the shooting.

Authorities have not publicly identified the deputy involved.

No deputies were reported injured.

The sheriff's description represents the preliminary findings of the law enforcement investigation, which remains active.

Two children rescued

After Fabrizio was shot, deputies entered the home and removed the 16-year-old girl and her 14-year-old brother to safety.

Both children survived and are now in the care of family members, according to the sheriff's office.

Authorities are withholding their identities because they are juveniles.

Deputies then searched the residence and found David and Monica Will dead from gunshot wounds.

Investigators reconstruct shootings

Dougherty said investigators developed a preliminary account of what happened using physical evidence and interviews with the surviving children.

According to the sheriff, investigators believe Fabrizio approached the front porch of the home and fired through a front window.

Those shots allegedly struck Monica Will.

Investigators believe Fabrizio then kicked in the door and entered the residence.

Dougherty said David Will was apparently near the door or the bottom of a staircase when Fabrizio allegedly fired at him.

Both adults died at the scene.

The sheriff's office has characterized the deaths as homicides.

Possible dispute involving teenage daughter

Investigators believe Fabrizio had grievances involving David and Monica Will and had an interest in their juvenile daughter.

Dougherty told MetroNews that Fabrizio and the girl had met through church.

The sheriff said investigators believe the Wills had forbidden Fabrizio, who was 25, from dating their teenage daughter.

Dougherty said investigators currently believe that dispute was the catalyst for the violence.

The investigation is continuing, and authorities have not indicated whether other factors may also have contributed.

Because Fabrizio died at the scene, the allegations against him will not be tested through a criminal trial.

Sheriff says incident was isolated

The sheriff's office said investigators believe the violence was isolated and that there is no continuing threat to the surrounding community related to the incident.

Middle Grave Creek Road runs through a rural area of Marshall County outside Moundsville in West Virginia's Northern Panhandle.

Marshall County is part of the Wheeling metropolitan area and sits along the Ohio River.

The sheriff's office said the scene and evidence remain part of an active investigation.

West Virginia State Police are participating in that investigation.

School community affected

Marshall County Schools announced Thursday that one of its teachers had been killed and said counseling would be available for students and staff at John Marshall High School.

The district canceled all academic, athletic and adult-education activities at John Marshall High School for Thursday.

Classes are expected to resume Friday.

The school's homecoming parade was also canceled, while other homecoming and school-sponsored activities were expected to proceed beginning Friday.

The district asked the community to support the victim's children, family members and school community.

Deputy shooting also under investigation

The fatal shooting of Fabrizio by the responding deputy is being investigated separately as part of the overall case.

Dougherty said the deputy fired after observing Fabrizio holding the teenage girl at gunpoint.

Investigators will examine the deputy's actions, evidence from the scene, witness accounts and the sequence of events leading to the shooting.

The West Virginia State Police are involved in the investigation alongside the Marshall County Sheriff's Office.

No additional information about the deputy's administrative status had been announced in the reports reviewed Thursday afternoon.

Three deaths in one incident

The incident ultimately left three adults dead: David Will, Monica Will and Cyle Fabrizio.

The Wills' two teenage children survived.

Authorities say one of those children was being held at gunpoint immediately before a deputy shot Fabrizio.

No additional suspects have been announced.

Investigators have not indicated that anyone else participated in the killings.

What remains under investigation

Authorities are continuing to examine the exact sequence of events inside and outside the home.

Investigators are expected to review ballistic evidence, the firearm or firearms recovered at the scene, the 911 call, statements from witnesses and any available electronic or physical evidence.

The sheriff's office has not yet released a complete timeline showing how much time elapsed between the original 911 call, the deputies' arrival, the exchange of gunfire and the discovery of the two homicide victims.

Authorities also have not publicly detailed whether Fabrizio had any prior criminal history, whether police had previously responded to disputes involving the family or how Fabrizio arrived at the residence.

Those unanswered questions remain part of the active investigation.

The Marshall County Sheriff's Office said additional information will be released as it becomes available.
