Joran van der Sloot has a court hearing on Wednesday in which the family of Natalee Holloway could learn more about how their daughter died.

A plea deal will be considered during the hearing. NBC's "Today" spoke with attorney John Q. Kelly, representing the Holloway family, who said the plea deal has a condition in which Van der Sloot must reveal how Holloway died and how her body was disposed of.

Van der Sloot pleaded not guilty to extortion and wire fraud charges in a Jefferson County court this past June. He has not been charged with her murder.

Natalee Holloway was on a senior trip to Aruba when she disappeared on May 30, 2005. She has since been declared dead, but the body of the 18-year-old was never found.

In 2010, van der Sloot was federally charged for allegedly taking $25,000 from Holloway's family in exchange for information leading to her body. He is already serving a 28-year sentence in Peru for the unrelated murder of Stephany Flores.

The hearing on Wednesday is scheduled for 9:30 a.m. at the Hugo L. Black Courthouse in Birmingham. Judge Anna M. Manasco is presiding.
