Judge Pat Siracusa agreed with prosecutors Reeves, 71, should not be able to leave custody in Pasco County jail, CNN reported.
Prosecutors earlier played a surveillance video at a hearing suggesting Reeves was struck before shooting a man to death.
At the Dade City bail hearing for Reeves -- charged with second-degree murder and aggravated battery with a firearm in the Jan. 13 shooting death in a movie theater of Chad Oulson, 43 -- defense attorney Richard Escobar said the object that struck Reeves was Oulson's cellphone.
Reeves' attorneys claim he acted in self-defense after he was pelted with popcorn and had the object thrown at him during the dispute with Oulson over texting, prior to the movie.
Reeves, a decorated retired police officer, claims he was assaulted by Oulson in the theater before he fired at Oulson, the Tampa Bay Times reported.
Reeves' next court hearing is March 12.
