Recorded jail-phone calls led to the arrests of Donna Sue Adelson, 73, at the Miami International Airport. Adelson, 73, a woman implicated in hiring a man to kill her former son-in-law, Florida law professor Dan Markel, was arrested at the Miami International Airport. She had booked airline tickets with her husband to Vietnam, which does not have an extradition treaty with the U.S., according to jail records and an arrest warrant obtained Tuesday by NBC News.
Adelson's son, Charles Adelson, a Florida dentist, was convicted earlier this month in the murder-for-hire plot that left Florida State University law professor Dan Markel dead. After her son's Nov. 6 conviction, Donna Adelson told her son that she was considering leaving the country with her husband and discussed non-extradiction countries in the calls. Her husband was not arrested. Authorities said the killing stemmed from a dispute between Markel and his ex-wife, Wendi Adelson — Donna Adelson's daughter -- over the custody agreement for their two children and that Donna Adelson, wanted Markel to move her grandchildren closer to her, even offering $1 million to do so. The arrest warrant describes Donna Adelson and her husband as having the means to pay a hitman to kill Markel.
