A combination of good policing and a bit of luck led to the arrest of two capital murder suspects just minutes after an early morning killing, Police Chief William McManus said Wednesday.

“This is nothing less than a cold-blooded murder, the kind seldom seen here,” McManus said, describing the incident as a failed robbery in which a woman was shot several times in the back as she attempted to flee her assailants.

The Bexar County medical examiner identified the victim as Cecilia Tijerina, 41, who was pronounced dead at the scene.

Each of the men was booked on a single count of capital murder. If convicted, Adam Rincon, 21, and Rickey Lynn Flowers Jr., 29, could face the death penalty.

They were ordered held in Bexar County Jail under $1 million bail each.

McManus said investigators have linked the pair to at least one other incident Tuesday evening in which a woman was the target of an armed robbery after being approached by a pair fitting the arrested men's description.

A police spokesman said officers are looking at two other incidents Tuesday night that fit the same pattern: two men in a pickup approaching a woman on the street and demanding money after brandishing a gun.

“We are confident and optimistic that these are the right suspects,” McManus said at a news conference.

Investigators said two men were in a pickup at a dead end in the 1100 block of Rivas near Zarzamora Street about 1:30 a.m. Wednesday when one of them approached Tijerina in what police said was a robbery attempt.

McManus said a witness reported that the woman told her assailants she didn't have any money, then turned and was attempting to run away when she was shot in the back. At least three shots were fired; she was hit twice, in the back and in the left shoulder, a police report states.

Just a few minutes later, a police sergeant heard the bulletin broadcasting a description of the truck and occupants and noticed a truck that fit the description drive by his location, the report adds.

The sergeant, Curtis Coolidge, stopped and detained the duo at West Commerce Street and North San Jacinto Street, less than a mile from the crime scene.

Police said a small-caliber hand gun was found under the truck's seat that is believed to have been used in the shooting.

It wasn't immediately clear if the men knew the victim; police earlier indicated that suspected prostitutes may have been being targeted.

McManus, however, said detectives hadn't yet established what Tijerina and the other women were doing at the time they were approached.

McManus said the capital murder charges were filed because the woman was killed allegedly during the commission of a felony, the armed robbery.
