Footage has been released of the murder of a well-known Columbian journalist gunned down in broad daylight.
Radio presenter Flor Alba Nunez Vargas (25) was shot in the head by a masked assassin as she arrived for work last Thursday morning.
The video shows a hitman creep up behind the young journalist as she waits by the door of her radio station in Huila, south west Colombia, before killing her with a single shot.
The CCTV footage goes on to show the gunman calmly walking away from the brutal murder before getting on a motorbike and driving away.
The Colombian government has announced a cash reward for information leading to the arrest of the killers.
Ms Flor, 25, was known as a campaigner against drugs and people trafficking and corruption.
She had recently received death threats on Facebook over her recent local election coverage and for publishing the picture of a criminal gang blamed for a town hall break-in.
She is also said to have been threatened after interviewing suspects linked to the murder of a dog last month.
Shortly before her death she retweeted a link to an interview with a Colombian bishop who claimed: "All politicians are liars."
Huila Police chief Santiago Camelo blamed the crime on contract killers and appealed for the local community to come forward with information.
He said: "We are on the trail of the murderer who appears to have escaped by motorbike.
"We cannot at this stage specify the cause of this terrible event.”
The 25-year-old hosted a popular programme called La Preferida Stereo on the radio station called La Preferida FM.
Her radio station described her as a "passionate journalist" and said in a statement: "We profoundly regret the murder of our companion.”
"We hope this doesn't remain as just another unpunished crime. Peace in death."
Ms Flor's murder comes three weeks after a Brazilian radio presenter was killed live on air by two gunmen who forced their way into his recording studio.
Father-of-two Gleydson Carvalho, a critic of local government corruption, was shot three times in the head and chest on August 6 at Radio Liberdade FM in the north-eastern beach resort of Camocim.
