DFR units were dispatched shortly after 3:00 a.m. to the location for a fire alarm resulting from several small fires that were set on the first and second floors of the building.

Residents were evacuated from the building while firefighters, police officers and the bomb squad addressed everything from spot fires to investigating a bag that was found outside of an apartment unit on the third floor; which turned to be harmless, DFR said in a statement.

Fire investigators and police officers worked in conjunction with building management, witnesses and associates to quickly identify Gilliland, using surveillance footage.

They notified fire investigators, who responded to the scene and took him into custody.

During his interview, DFR said he admitted to setting the fires because of mounting frustrations over undisclosed personal circumstances.
