The man suspected of committing four homicides in Jefferson and St. Clair counties on Tuesday was arrested Friday in connection with the killings of a man and a woman in Birmingham.

The Jefferson County District Attorney’s Office issued an arrest warrant Friday for capital murder for Daniel P. Watson, 28, of Pell City, in the Tuesday slayings of Tiffany Michele Hernandez and Jason Joseph Brown, both 40 and from Birmingham, said Officer Truman Fitzgerald with Birmingham police.

Watson’s warrant was for capital murder because the killings involved multiple victims.

Hernandez and Brown were found shot to death Tuesday at a home in South East Lake.

They are believed to be the first pair of slayings committed by Watson on Tuesday, according to Fitzgerald.

Watson allegedly later committed another double homicide in St. Clair County, when he shot and killed Amber L. Manning, a 37-year-old wife and mother, and Timothy R. Davidson, a 62-year-old father, at a home on Ivy Drive in Ragland, according to St. Clair County Sheriff Billy Murray.

When St. Clair County sheriff’s deputies arrived at the home while responding to a disturbance there, they found Manning, dead in the driveway.

Davidson was inside the residence and still alive. He was flown by lifesaver to UAB hospital and later pronounced dead.

Watson knew at least some of the victims.

“From everything that I’ve been told, the suspect knows everybody or knows of everybody. You’re dealing with four lives lost in 24 hours and a potential fifth life lost in the end once this case goes to trial,” Fitzgerald said.
