● Shoots Fired At Two Offices In Birmingham Suburb

● Unnamed Suspect In Custody After Scuffle

● Two Victims Were Co-workers Of Suspect

The 34-year-old suspect, who was not immediately named, was arrested "after a brief scuffle" when officers forced his car to a shoulder of I-65 in nearby Chilton County.

Pelham Police Chief Allan Wade said the suspect worked at Ferguson Enterprises, where the first two victims were shot inside the business. Officers were summoned to that scene at 7:04 a.m. ET and were securing it when Pelham’s 911 dispatcher got a second call of a shooting at Post Airgas. The third victim was found there.

Wade said the suspected gunman at Post Airgas matched the description of the killer who fled Ferguson Enterprises and that his car was spotted entering the interstate at nearby Alabaster.

No one was seriously injured in making the arrest on the side of the highway. A handgun was found on the seat of the suspect’s car, said Wade. The victims were identified as Lee Holbrooks, 32, of Pelham, Christopher Yancey, 28, of Alabaster, and Terry Jarvis, 39, of Montevallo.

Wade said the suspect was from Billingsley, a rural town in Autauga County about 50 miles south of Pelham.

Pelham, a city of about 10,000, is part of sprawling suburbs in the wooded hills south of Birmingham. The area is a mix of upscale subdivisions, commercial districts and rural farmland spotted with businesses.

Wade said Holbrooks and Yancey were employees at Ferguson Enterprises and that Jarvis worked at Post Airgas.

Philadelphia-based Post Airgas sells specialty gases, like helium and oxygen, to hospitals and individuals. Ferguson Enterprises, based in Newport News, Va., is a wholesale distributor of plumbing and lighting fixtures.

The shootings came one week after frustrated day trader Mark O. Barton fatally shot nine people and injured 13 others at two brokerage firms in Atlanta in one of the worst office massacres ever. Pelham is 144 miles west of Atlanta.

Fred Leder, a day trader at All-Tech who sat next to Mark Barton for nine months, was released from the hospital Wednesday.

"To a degree it’s really frightening that all of a sudden someone is copying this, I can’t believe some idiot has started to copy it," he said.
