TAMPA — When an officer working for Critical Intervention Services was killed while patrolling a St. Petersburg apartment complex in May 2011, the company offered a reward for information.
Days later, officers arrested Bradley Bolden on charges he killed the 26-year-old officer, Mathew F. Little.
On Tuesday, nearly a week after another security officer was slain in the line of duty, CIS president K.C. Poulin announced a $10,000 reward for information leading to an arrest in Michael Valentin's slaying.
"We ask the community to help us take this individual off the streets," Poulin said. "There is no question that if he is willing to do that to an armed, trained security officer, he has no fear of doing that to anyone else within the community."
Valentin, a 38-year-old married father of two sons, was working as a security officer Nov. 21 at Grande Oaks Apartments, 8450 Standish Bend Drive, when he was killed, Tampa police said.
Valentin was armed, but his gun was still in its holster when a police officer checking out a report at the complex discovered his body on a sidewalk outside the clubhouse.
Police have not disclosed the cause of death, only saying that Valentin sustained "upper body trauma."
The motive remains unknown.
"His life was tragically taken," said Tampa police Maj. Brian Dugan. "We have been working this case since then nonstop. Our detectives worked right through the holidays to get to the bottom of this."
Dugan said detectives have continued to interview residents at the complex.
They recovered an orange and black bicycle near Valentin's body, which is being tested for fingerprints.
Police also released video surveillance during the weekend that captured a man wearing a bandana that he periodically used to cover his face while riding a bike on a nearby street. Detectives have sent the video to the FBI for enhancement.
Police and CIS officers have also strengthened their presence at the apartment complex, where residents have been cooperative with detectives, Dugan said.
An event commemorating Valentin is scheduled to take place at Grande Oaks Apartments from 3 to 6 p.m. today.
Services for Valentin will be held at 10 a.m. Friday at St. Mark the Evangelist Catholic Church.
"Our staff and the family have taken it very hard," Poulin said as he held back tears. "It's a tough situation for all of us."
