The Tampa Police Department is using horse patrols in a neighborhood that's been plagued by homicides in recent weeks.
Officials in Tampa have been searching for the person -- or people -- who they say are responsible for shooting and killing four people in the Seminole Heights neighborhood since Oct. 9.
Police said the shootings, which happened within proximity of each other, weren't robberies and could be the work of a serial killer.
The homicides have left residents scared and city officials frustrated because there hasn't been an arrest, despite a reward of more than $100,000 for information to help solve the case.
The department has received some 1,100 tips.
The mounted horse patrols in the neighborhood began Friday and will continue through the weekend.
