An attorney working as a public ombud in the southwestern Colombian town of Puerto Tejada was gunned down outside her home, authorities said Tuesday.

Hilda Myriam Lasso Largacha, 59, was killed by two assailants as she arrived home Monday night, the government of Cauca province said in a statement.

"No threats against her are known, nor was there a sign that anything related to her work might endanger her," provincial chief ombud Mauricio Redondo said.

"We never had calls complaining about her work - she was always punctual with her reports, she never missed a hearing, and she was an excellent public defender," he said of his slain colleague.

Redondo urged Puerto Tejada Mayor Gustavo Alberto Hincapie to convene a security council to analyze the situation and ask authorities for details about the circumstances surrounding the murder.

Cauca, one of the most violent provinces in the country, has 76 public ombuds who attend cases from domestic problems to incidents related to Colombia's decades-long internal armed conflict.

The national ombud, Jorge Armando Otalora Gomez, decried the attorney's murder and said that Lasso was always characterized by being very disciplined in her work.

Otalora Gomez expressed his concern because Lasso is the third ombud to be murdered since November. EFE
