TALLAHASSEE, Fla. (AP) - Tallahassee Police say a Florida State University professor found at his home after an attack last week was shot in the head before dying at the hospital.

Spokesman David Northway says there are no suspects, and the department continues to ask for tips from the public.

Officers found College of Law Professor Dan Markel on Friday morning and believe he was the intended target.

Northway said the department has received many calls to the tip line but would not provide other details of the case. He declined comment when asked if there was evidence of more than one gunshot and if there were signs of forced entry. 

Crimestoppers has increased the reward for information leading to an arrest from $1,000 to $3,000.
