ORLANDO, Fla. -- The state released over 1,100 pages of evidence to Casey Anthony's defense team on Monday.

According to a source close to the investigation, test results from the FBI crime lab on the duct tape found on slain toddler Caylee Anthony's skull are in that new batch of evidence.

When asked by WESH 2's Bob Kealing if Casey Anthony's fingerprints were on the duct tape, a source with direct knowledge of the investigation said, "This is not going to be good news for the defense."

A spokeswoman with the state attorney's office told WESH 2 she does not plan to release this new evidence released to the public until at least midweek.

Orlando defense attorney Richard Hornsby said the duct tape evidence brings the possibility of the death penalty back in to play. Hornsby said it may force Anthony's defense attorney, Jose Baez, to "put Casey on the stand" or "consider a plea bargain."...
