Smith was taken into custody without incident Sunday, CBS DFW reports. He was transported to the Crimes Against Persons Division and interviewed by homicide detectives. During the interview, the suspect allegedly admitted his participation in the crime.

According to KTHV, Dallas police said Smith allegedly went to the home to conduct unspecified "business," and got into an argument that caused him to start shooting. In addition to the three fatalities, a fourth victim was shot in the head; police said she played possum until the suspect left. That victim was later taken to a hospital for treatment.

The suspect also allegedly shot at a fifth person, KTHV reports, and even tried to run him or her over with his car, but was unsuccessful.

Smith faces capital murder charges and is currently being held at the Dallas County Sheriff's Department. His bond is set at $1 million.
