The ex-wife of a slain Florida State University law professor and her family on Wednesday denied having any involvement in an alleged murder-for-hire plot to kill him, according to a statement issued by their lawyers.

Attorneys for Wendi Adelson and several family members said in the statement that speculation they had a role in Dan Markel’s killing is “categorically false.” Authorities have previously said there may be a link between Markel’s July 2014 slaying and the couple’s contentious divorce.
