LEHIGH ACRES, Fla. - There are new details available in the murder of a Lehigh Acres woman, who was found dead around 9:30 a.m. on Wednesday, May 12, 2010. Police say the victim's body was tied to the undercarriage of the suspect's car, her remains dragged from her home to a lot across the street. That's where the woman's remains were recovered.

The victim has been identified as Maria DeLourdes Bauza, age 48, a resident of 3405 21st Street SW in Lehigh Acres. The suspect: her husband --  58-year-old Zacarias Jaime Izquierdo. He's now charged with first degree murder. 

Police were initially called to the Lehigh neighborhood when a neighbor saw a blood-covered Izquierdo exiting the car in the field and "staggering" toward his nearby home. The witness spotted a significant amount of blood on the home's driveway; police would later learn the morbid details surrounding how the blood ended up on the pavement.

According to police reports from the Lee County Sheriff's Office, Izquierdo admitted to the murder of his wife. He told investigators that he had been engaged in a dispute with his wife; he alleged that his wife had struck him with a shovel, but investigators learned that the shovel in question had been at the home of a neighbor; the neighbor confirmed that he had borrowed the shovel about four weeks prior. In addition, an exam of the suspect revealed no bruising, marks or other injuries that one would expect to see in a person who had been struck with a shovel.

Police reports say that Izquierdo retrieved his AK-47 semi-automatic assault rifle from a bedroom closet; he retrieved a magazine from another location in the home and loaded the weapon.

Izquierdo says he approached his wife with the AK-47 concealed g his leg. She was working on the computer in the dining room/kitchen area of the home when Izquierdo approached. Standing about 10 feet away from the victim, he told police that he called her name and stated, "Now you're going to pay for what you've done to me." When Bauza saw the weapon, she started running toward the garage. Izquierdo opened fire, shooting Bauza several times. She collapsed and died on the garage floor.

Izquierdo reportedly told investigators that he tried to lift his wife's body into the car, but was unable to do accomplish the task. So he used an extension cord to tie Bauza's dead body to the undercarriage of his dark blue compact car.

In an attempt to dispose of his wife's remains, police say Izquierdo drove to the adjacent lot, dragging his wife's remains on the ground. He left the car in a lot, with the woman's body still tied to to the undercarriage. He then walked back inside his home, where he was approached by police a short time later.

Izquierdo remains in police custody on first degree murder charges.
