( CNN ) -- Days after a nationally renowned criminal law professor was found with a gunshot wound to his head , his death is being investigated as a homicide . Florida State University professor Dan Markel was found in his Tallahassee , Florida , home on Friday . Police say there were no signs of robbery or burglary and have yet to disclose any motive . According to Tallahassee police , officers found Markel after a neighbor called 911 at about 11 a.m. with reports of a `` loud bang . '' Markel , 41 , was rushed to a local hospital , where he died the following day . `` While we can not release specific information or details regarding this case , the Violent Crimes Unit is releasing that Mr. Markel 's cause of death was a fatal gunshot wound to the head , '' Tallahassee Police Chief Michael DeLeo said in a statement . By Monday , police had categorized the case as a homicide , and according to Tallahassee Police Department spokesman David Northway , Markel was the intended target . Police created a tip line and offered a $ 3,000 reward . Within 24 hours , authorities received several leads , which they are pursuing , Northway said . Authorities are also asking anyone who was in Markel 's neighborhood between 10 a.m. and noon Friday to contact police . `` This includes delivery drivers , visitors to the neighborhood or even pedestrians that were walking in the area who may have seen or heard anything that would lead investigators to the suspect in this case , '' a police news release says . Though police assured the community that Markel 's killing was not likely a random act , there was still confusion and concern in Tallahassee . `` We were all shocked , '' former student Tony Fusco told CNN affiliate WCTV . `` We did n't know why . We did n't know how . We just heard he was gone , and it was a big shock to all of us . '' According to the university , Markel began working at FSU in 2005 after receiving his bachelor 's at Harvard College , a master 's from the University of Cambridge and a law degree from Harvard . During his FSU tenure , the Toronto native taught several classes and wrote extensively about criminal law , including articles published in the Yale Law Review , among others . Markel also founded PrawfsBlawg , a blog focused on law and life , and his writing appeared in publications such as The New York Times , Slate , The Jerusalem Post and The Atlantic Monthly . On Sunday , friends , family members , students and colleagues gathered at a Tallahassee synagogue to remember the father and scholar , according to WCTV . `` I am filled with awe and appreciation for the support of our friends and family and particularly for the show of admiration , respect and love for Danny from this Tallahassee family , '' his sister , Shelly Markel , said , according to the station . On the PrawfsBlawg front page , 10 fellow law professors posted about the respect they had for Markel and the mutual love he shared with his friends and family . `` His boundless energy was at the center of this community ; it made it run , it gave it life . We are stunned and bereaved by his loss , and our thoughts go to his two little boys , who were precious to him , and to his family . '' Florida State also issued a statement , saying in part : `` His contributions to Florida State University College of Law and the broader legal community are pervasive and lasting . ... We will feel his loss for many years to come . '' Markel was divorced from fellow FSU law professor Wendi Adelson last summer , according to her attorney , Jimmy Judkins . `` She is a basket case , distraught , very emotional , '' said Judkins , who told CNN his client has no idea why this happened . Police have been in contact with Adelson , the attorney said . Three New Mexico teens charged with killing homeless men . New York man dies after chokehold by police .
