A holiday weekend turned tragic Sunday morning as a shooting incident left two people dead in Apex.

Guadalupe Rosas, 59, of Apex was shot and killed by a man she had a relationship with five years ago.

The suspect, whose name is still not being released until the notification of next of kin, died of a self-inflicted gunshot. Police do not believe he lives in the Apex area.

Apex police officers responded to an “active shooting” about 11:35 a.m. at the Super Target in Beaver Creek Commons.

When officers arrived they found Rosas dead in the front of the store. She had been shot multiple times.

Rosas, an employee at Super Target for approximately two years, was standing at her cash register when she was killed.

The suspect was still holding a handgun when confronted by police.

“When our officers arrived on scene they went inside the store and saw the suspect,” said Capt. Ann Stephens of the Apex Police Department. “The victim had already been shot. The suspect was standing there with a handgun. Our officers challenged the suspect to put down the gun. At that time he turned the weapon on himself and shot and killed himself.”

Employees and customers were still in the store when police arrived and were attempting to flee the scene. Four people sustained minor injuries making their escape.

Police believe Rosas and her killer had a relationship that ended in 2005.

“The suspect had stayed in touch with the victim,” said Stephens. “He showed up at the Target store today with a handgun and shot and killed the victim inside the Target store.”

Police are still unsure what prompted the shooting.

Law enforcement agencies from Apex, Cary, Holly Springs and the Wake County Sheriff’s Department responded to the incident.
