Blood-stained car parts and a forensic analyst's description offered a Texas jury a startling glimpse into the last hours of a homeless man impaled on a windshield and left in the accused killer's garage, where he died.

As the second day of testimony in the Fort Worth, Texas, trial of Chante Mallard got underway Tuesday, analyst Max Courtney described blood spatters found in the car from the victim, Gregory Biggs, 37.

Mallard faces life in prison for striking Biggs while driving her 1997 Chevrolet Cavalier and continuing home with Biggs stuck in her windshield. Once home, she parked the car inside her garage, and contacted friends rather than authorities.

Courtney attempted to recreate the scene for jurors,  describing, for example, how cuts on Biggs' fingers alone resulted in a side-door pocket compartment full of blood.

Patterns in other areas of the vehicle also had stories to tell, such as one blood spatter on the console that the victim could have breathed out.

"It would come from a gasp or a wheeze or whatever was being expelled from the victim's mouth," said Courtney, who throughout his testimony illustrated his points by pointing out specific spatters on the car parts themselves.

Courtney also offered a graphic picture of how Gregory Biggs' twisted body was positioned as he bled.

"I would say it was consistent with the head being toward the back of the passenger front seat, the left hand into the pocket compartment of the passenger door," Courtney testified. 

The vehicle wasn't discovered by police until months after the Oct. 26, 2001, crash that ultimately led to Biggs' death. His body was found the next day in a nearby park. Mallard, 27, was arrested when an acquaintance of the defendant tipped off police. 

At the time of Mallard's arrest, police discovered the car still parked in her garage with much of the windshield knocked out and a seat missing, which they later discovered had been burned.

With remnants of the windshield left behind, Courtney said he found several hair fragments that are "typical of Caucasian hair." Biggs was white, and Mallard is black. Also recovered was a hammer in the backseat, which Courtney testified was used to break the glass.

His testimony came a day after a friend of Mallard's took the stand and described seeing Biggs in the garage while he was still alive. Titilisee Fry testified she demanded Mallard call 911 as Biggs lay dying, but said the defendant refused.

Also expected to testify for the prosecution are two men who admitted disposing of Biggs' body. Clete Deneal Jackson and Herbert Tyrone Cleveland pleaded guilty to evidence tampering and are serving 10- and 9-year sentences, respectively. 

Testimony was scheduled to resume Tuesday afternoon and is being aired on Court TV.
