Adelson was arrested at Miami International Airport in an alleged attempt to flee to a non-extradition country.

Investigators believe Adelson had Markel killed following the divorce from her daughter, Wendi, after a judge and Dan denied her request to move herself and the two children to South Florida, closer to her family.

Donna Adelson is the fifth person charged in the murder-for-hire plot of her former son-in-law, a Florida State University law professor and well-known throughout Tallahassee. The first person brought to justice, Luis Rivera, agreed to a plea deal.

Rivera testifies he and his lifelong friend, Sigfredo Garcia, drove from Miami to Tallahassee to carry out the hit, and Garcia was the trigger man. Rivera, once a Latin Kings gang leader, accepted a 19-year prison sentence in exchange for flipping on his close friend.

This week, in Donna Adelson’s trial, some of the most dynamic pieces of evidence are the money changing hands and the wiretaps. Mary Hull, from the Florida Department of Financial Services, breaks down financial records before and after the murder of Dan Markel.

Rivera admits on the stand he received over $33,000 for the hit. Also, the jury hears the feds’ wiretaps, Charlie and Donna Adelson talk in code, and the bump, which was orchestrated to trap the co-conspirators into a phone frenzy.
