Glenda Coca-Romero's father pleads with her killers

(WJLA) - Too young to know what happened to her mother, and too innocent to grasp the violence, the 10-month-old daughter of 21-year-old Glenda Coca-Romero was held by her grandfather as he pleaded with three killers.

"Whoever committed this crime -- [I need] for them to have some consciousness of what they did," he said via an interpreter.

On February 21 at about 9 p.m., three men barged into a Woodbridge grocery store wearing dark clothing and covering their faces. In just seconds, they raced through the store, shooting two female employees. They killed Glenda Coca-Romero and injured her 42-year-old co-worker.

Then, as abruptly as they entered, the suspects took off.

Investigators are baffled, as the suspects left with nothing.

“You have three gentlemen come in the store and they are in and out in nine seconds -- and in their wake, you have a 21-year-old woman who is dead and another in the hospital; it doesn't make sense," said Assistant Chief Major Steve Thompson with Prince William County Police.

Officials have called on the FBI for help, and the Feds are also kicking in extra cash to hike up the reward for vital information to $11,000.

Coca-Romero’s father says he has no idea why anyone would want to harm his daughter:

"She just worked and didn't party or do anything like that -- her thing was to work and take care of her child."

Meanwhile, Irene Coca continues to grieve for his daughter, hoping for answers and justice. He also pledges to care for his granddaughter, Brittni.
