POLICE say a scorned woman is the mastermind behind the murder of an entire family last year. Ahora, she’s behind bars.

Alexus Chenelle Williams, 29 is facing three counts of capital murder in the shooting deaths of Gregory Carhee, 35, Donyavia Lagway, 29, and Harmony Carhee, 6.

Según autoridades, the Texas woman allegedly hired a hitman, Xavier Davies, 28, to do the job. He has been charged with three counts of capital murder and aggravated assault with a deadly weapon.

At the time of the incident, Lagway was pregnant and living with her husband and daughter.

Police believe Williams and Lagway started an extramarital affair but Lagway had ended things and returned back to her husband.

En represalia, Williams allegedly hired Davies to kill Lagway and the entire family.

“We believe their relationship ended badly about a week before these murders,” said Prosecutor Sean Teare with the Harris County District Attorney’s Office.

Shockingly enough, the Houston Chronicle reports that Williams might have watched the murdered on her phone through FaceTime.

“He was on FaceTime with Alexus Williams. That means she watched either the executions or the immediate aftermath of that family being wiped out,” said Teare.

It’s believed Williams allegedly enticed Davies with all the money inside the apartment if he committed the murders.

The family’s 10-year-old daughter survived the attack but was critically injured. The girl reportedly played dead while protecting her infant brother after the alleged killer threw him across the room.

The girl then called her grandmother over FaceTime to get some help.

Williams is scheduled to see the county judge on Friday morning for a bail hearing, it’s expected that prosecutors will petition to have her held without bail.
