Nancy Grace

Internet searches, texts and Facebook messages implicate a Florida couple in the murder of an 18-year-old friend in their Fort Lauderdale apartment, according to police.

Court documents allege that 32-year-old James Ayers and 23-year-old Nicole Okrzesik discussed killing Juliana Mensch and argued over what to do with her body online and in text messages after authorities believe the teen was asphyxiated in the early hours of March 24. Mensch’s decomposing body was found under a pile of clothing in the apartment five days later.

The babysitter accused of hiding a 1-year-old Ohio boy’s body in a closet and falsely reporting him missing had been caring for him for about two weeks, his mother said Wednesday.

According to Kiara Carter, she and Marquita Burch were “like sisters” until last Friday. She said Burch had babysat 1-year-old William Cunningham for extended periods of time before, but she always brought him home whenever Carter asked.

Prominent forensic scientist Dr. Henry Lee said Friday that possible blood stains discovered by police in the Isabel Celis investigation could provide significant information.

Lee, well-known for his work on O.J. Simpson's defense team, told HLN's Nancy Grace that details contained in newly released police reports may be crucial to solving the mystery of the 6-year-old's disappearance.

Investigators have announced a major break in the disappearance of a 21-year-old University of Louisiana college student who was last seen riding her bike home from a friend’s house in the early morning hours of May 19.

Two fishermen discovered the missing co-ed’s bike Sunday morning under a bridge at the Atchafalaya River. The discovery was made approximately 27 miles from where Michaela “Mickey” Shunick was last seen.
