(CBS/WKMG/AP) ORLANDO, Fla.- Jurors in the Casey Anthony trial heard testimony about heart-shaped stickers and hair evidence Tuesday, as the prosecution neared the end of its case against the Florida mother accused of murdering her 2-year-old daughter Caylee.

Crime scene investigator Alina Burroughs testified that heart-shaped stickers were found in Casey Anthony's bedroom, but did not link them to testimony given Monday by FBI forensic examiner Elizabeth Fontaine. 

Fontaine testifiedabout the duct tape found with Caylee's skull and said she observed what appeared to be heart-shaped glue residue about the size of a dime on one of the pieces. Fontaine testified that testing the tape for fingerprints destroyed the residue and no photo was taken of it.

The prosecution said in their opening statement that they believe the outline was from a heart-shaped sticker.

Earlier Tuesday, Catherine Theisen, a forensic mitochondrial DNA analyst for the FBI and the quality assurance supervisor for the FBI laboratory, testified about hair samples, saying that hair from the trunk and hair from Caylee's skull were a mitochondrial match. That match could also be made to Casey Anthony, Casey's mother Cindy or anyone else in the maternal line, including Casey's brother Lee.

Prosecutors then called Cindy Anthony to the stand for a second time. Prosecutor Linda Drane Burdick asked Cindy Anthony about the length of her hair in July 2008, and whether it was colored, according to CBS affiliate WKMG.

Cindy Anthony testified that in 2008 she kept her hair short and dyed blond and that her son Lee kept his hair short as well. Cindy Anthony testified that she sometimes trimmed Caylee's hair but that she never colored it. She also said that Casey's natural hair color was brown but that she had colored it numerous times in the past, WKMG reported.

Casey Anthony is charged with first-degree murder in the death of her daughter and faces a death sentence if convicted. She has pleaded not guilty. Prosecutors contend Casey Anthony suffocated Caylee with duct tape, while the defense says she drowned in her grandparents' pool.

Caylee was not reported missing for 31 days. Her remains were found in a wooded area near the Anthony home in December 2008.

The Casey Anthony case was recently reported on by "48 Hours Mystery."
