WARNING: GRAPHIC DETAILS OF CRIME

RICHARDSON — Officers discovered the severed head of a young woman in a trash bag Saturday afternoon while investigating a disturbance in an upscale home on a quiet suburban street.

An officer "...located what he believed to be a severed human head with the skin of the face partially peeled off," according to court documents in the case.

The victim was identified as 20-year-old Ibonne Zamudio of Dallas.

On Saturday morning about 9:15 A.M., a 10-year-old boy called 911 "...claiming there were two males inside his house and a female that was being killed," the documents revealed.

The crime scene was in an upstairs bathroom. The head was in one of three black plastic trash bags.

James Matisi, the owner of the house in the 5700 block of Kensington Drive, was reportedly hiding in the master bedroom closet with his son, who called police.

Timothy Jones, left, Eric Ziegler, center, and James Matisi are being held on $1,000,000 bond each.

Officers said Timothy Jones, a suspect in the murder, was nude and belligerent as police entered the home after kicking down the front door.

Eric Ziegler was asleep in one of the bedrooms, police said.

According to Richardson police interviews with the suspects, Jones and Ziegler brought Zamudio to Matisi’s home in the middle of the night so all three could smoke crack.

But the early morning hours would soon turn violent.

Jones stated for a Probable Cause Affidavit that at some point, “…he went to the bathroom and found Eric Ziegler standing in the bathroom, and Zamudio was nude, dead, and lying in the bathtub with her head cut off.”

Jones said he originally thought Ziegler and Zamudio were in the bathroom having sex.

“Jones said that Ziegler was wild-eyed and high on drugs and Ziegler had already cut Zamudio’s scalp from her head," the affidavit statement read.

"Jones said that he watched Ziegler pull the shower curtain rod down from the wall. Jones saw Ziegler thrust the curtain rod into Zamudio’s eyes, jamming the curtain rod into her skull. Jones said that he was scared by Ziegler’s actions and said that Ziegler was cursing the dead body as Ziegler cut on her body with a lock-blade knife, and he would rant and rave about her tattoos.”

The document went on to say: “[Zamudio’s] hands, feet, scalp, one arm, both legs and tattoos had been cut from her body. The legs were also cut in half at the knees. One arm was still attached to her torso.”

Investigators found the body parts in three black trash bags.

Richardson police said they are still interrogating the three suspects to try and determine what role each played in the brutal slaying.

All three have been charged with Zamudio’s murder and are being held in the Richardson City Jail on a $1 million bond.

The motive is still uncertain, investigators said.

Matisi’s 10-year-old son is in custody of Child Protective Services.
