Photos of two young sisters' ripped shorts and T-shirts and a pile of debris damaged in a house fire were shown to jurors Thursday in the trial of a suspect in a deadly home invasion.

Connecticut police Sgt. Karen Gabianelli took the stand in the trial of Steven Hayes, who is charged with murder, sexual assault and other crimes in the deaths of Jennifer Hawke-Petit and her daughters, 17-year-old Hayley and 11-year-old Michaela. The trial of co-defendant Joshua Komisarjevsky is to begin after Hayes' trial concludes.

Prosecutors say Komisarjevsky saw Hawke-Petit and her daughters at a supermarket in July 2007 and followed them to their home in the affluent suburb of Cheshire. He returned later with Hayes, authorities say, and together they severely beat Dr. William Petit and killed his wife and daughters.

William Petit, the sole survivor of the home invasion, who was beaten and tied up in the basement but escaped before the fire was set, held his head facing down at times Thursday as prosecutors showed photo after photo of burned staircases and hallways throughout the house. Petit had sobbed during Wednesday's testimony as photos of his daughters' bodies were shown.

Evidence presented Thursday included photos that showed pieces of shorts worn by Hayley Petit and a nearly shredded T-shirt and partially burned shorts belonging to Michaela.

Prosecutors also showed photographs of a pickup truck they say was driven by Hayes that held items from the alleged burglary, including a purple knapsack embroidered with Hayley's name, a string of pearls in a plastic shopping bag and other jewelry.

Other pictures showed ropes and other restraints used to tie Michaela to the bed and cans of what Gabianelli said was accelerant used to set the fire, and one showed a bedroom where a telephone had been disconnected from the wall and drawers were pulled out of a bureau with clothes strewn around the room.

Hayes was in court Thursday, but his lawyer told the judge that Hayes had had seizure-like symptoms and urinated on himself Wednesday night. Lawyer Thomas Ullmann said defense lawyers are prepared to continue.

Both defendants face the possibility of the death penalty if convicted.

On Wednesday, prosecutors played chilling bank surveillance video showing Petit minutes before her death, reports CBS News correspondent Elaine Quijano.

Petit is seen withdrawing $15,000, nervously alerting a teller that she's getting money for men holding her family hostage.

Questions in court centered around why the police took so long to try to rescue the family. An officer testified that they were following hostage protocol, Quijano reported.

911 Tape (Bank Manager): We have a lady who is in our bank right now who says her husband and children are being held at their house. That if the police are told, they will kill her children and the husband.

By the time the police encountered the suspects outside the Petit home, 33 minutes later, Petit and her daughters - 11-year-old Mikayla and 17-year-old Hayley - were dead. Petit had been raped and strangled. Her daughters died after inhaling smoke as their home was set on fire. Her husband -- who had been beaten and bound - barely escaped to a neighbor's house.

911 Tape (Neighbor): I got Bill Petit here,whose hurt, my neighbor.

911 Tape (Officer): You two, get in the house, get in the house. I need the 101 here now. Head injury.
