Law enforcement officials have apprehended a suspect in connection with the horrific slayings of an Alabama woman, her pregnant teenage daughter, and her 12-year-old son. The victims were discovered bound in their residence on April 20.

According to local news outlet WALA, Mobile County Sheriff Paul Burch announced that 54-year-old William Graham Oliver faces eight counts of capital murder. He was taken into custody and jailed on Tuesday.

Earlier reports from Fox News Digital revealed that deputies from the Mobile County Sheriff’s Office responded to a distress call in Wilmer, Alabama, shortly after 2:30 a.m. on April 20. Officers found the three victims, each in separate rooms with their hands tied behind their backs.

The victims were identified as 46-year-old Lisa Gail Fields, who was stabbed; her 17-year-old daughter, Keziah Arionna Luker, who was shot; and her 12-year-old son, Thomas Cordelle Jr., who suffered a fatal throat wound that nearly resulted in decapitation.

Authorities confirmed the identities of the deceased as Lisa Fields and her children, Thomas Cordelle and Keziah Luker, who endured a violent end in their Alabama home, as reported by WALA.

Sheriff Burch characterized the crime scene as “brutal” and remarked on the chaotic state in which the home was found.

Luker’s 18-month-old child was found unharmed in the home. Her unborn child, which was seven or eight months along, also died.

The unborn child’s father, who works offshore, triggered the discovery after he could not reach Luker when he saw her phone activated on Life 360, the sheriff said. Another family member went to check on her and found the deceased family.

Burch said Oliver knew the family “for quite some time” and was inside the home “looking for something” the night before the bodies were found, according to the report.

“Very very tight timeline,” Burch told reporters. “Very solid circumstantial evidence at this point and we feel confident that we have the right man.”

Burch said investigators have pinpointed what Oliver was allegedly looking for and his motive, but did not release those details to the public, the outlet reported.

Shortly after the killings, investigators said they believed more than one person was involved in the killings because the victims had been subdued using zip ties and flex cuffs. It is unclear if any additional suspects have been identified.

Jail records show Oliver was charged with first-degree theft of property in 2020, with other arrests dating back to 1990.

The sheriff’s office did not immediately respond to inquiries from Fox News Digital.
