Tallahassee , Florida ( CNN ) -- For the past week , the mystery surrounding the killing of a nationally renowned law professor has baffled family and friends from Florida to Canada . Florida State University Professor Daniel Markel was shot in the head at his home on July 18 and died a day later at a local hospital . On Friday , a day after Markel was laid to rest in Toronto , a few new details emerged in a heavily redacted police report . The report shows Markel , 41 , was shot in the garage of his home , some time between 10:45 a.m. and 11:02 a.m . The keys were inside Markel 's car , with the doors unlocked . The report also states there was no sign of forced entry , which Tallahassee police spokesman David Northway tells CNN could mean Markel knew the shooter . The report does not state whether the garage door was open . Police on Wednesday released via social media a picture of a silver car they term a `` vehicle of interest . '' Police on Facebook cautioned it may have been a resident , passerby or delivery driver . A neighbor told police a white or silver vehicle left the home , describing it as a Toyota Prius , or a Prius `` type '' of vehicle . Northway told CNN investigators used a nearby business ' surveillance camera to capture an image of what appears to be a Prius . Police say there were no signs of a robbery and have yet to disclose a possible motive . They have been following up on more than 50 leads and offered a $ 3,000 reward for information leading to an arrest . In a press release Friday , Tallahassee Police Chief Michael J. DeLeo said , `` Our investigators are using all resources available to them and are continuing to explore all of the tips that we have received . '' Police have been in contact with Markel 's former wife , Wendi Adelson , also an FSU law professor , said her attorney , Jimmy Judkins . She is `` scared to death '' that the killer may be targeting her entire family , said Allen Grossman , a close family friend , who has known the couple for several years . The couple have two young sons . Judkins earlier this week told CNN his client has no idea why this happened . 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 PrawfsBlawg , 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 . ''
Daniel Markel was found fatally wounded in his home 's garage . There were no signs of robbery or burglary . White or silver car believed to be near the scene . A man who lives on a street that runs parallel with the one where the shooting occurred said he heard gunshots and saw people running from the scene.
