A manhunt has ended after police found the suspect who allegedly murdered his sister and two others inside a Lakeland, Florida home over the weekend.

According to WTSP, David E. Smith was found by authorities in Knoxville, Tennessee and SWAT officers have been called to the scene to negotiate with him.

WFTV reported that the bodies of Ni'Kosi Williams, Miranda Mims and Smith’s sister, Danyala, were found in the home late Monday night.

Police began searching for Smith after he stole his father’s car and went on the run. The 27-year-old’s family members said that he suffers from Post-Traumatic Stress Disorder and had stopped taking his medication.

Polk County Sheriff Grady Judd said that the triple-murder suspect also had some questionable postings on his Facebook page where he talked about hating and destroying evil on his earth. He also posted delusional thoughts about his “adulterous wife.” He is not and has never been married.

Authorities said that Smith lived at the home with those he is suspected of killing.
