The Florida trial of Casey Anthony, who's accused of killing her daughter, will resume a day after the defense attacked forensics evidence previously offered by the prosecution.

Judge Belvin Perry says Wednesday will only be a half-day because he must attend a judge's meeting.

Forensic botanist Jane Bock testified Tuesday that 2-year-old Caylee Anthony's skeletal remains could have been in the woods for as little as two weeks when they were discovered in December 2008, a much shorter time period than prosecutors allege.

But the defense team also suffered a setback when Judge Perry ruled that a defense DNA expert could not testify about decomposition evidence found in Anthony's trunk until a hearing is held.

Casey Anthony is charged with first-degree murder in Caylee's death and has pleaded not guilty.
