Claim
Seventeen years later it evolved into the M-19 Democratic Alliance, a political party.
Correction

The timeline is off. Petro joined M-19 at age 17 (around 1977), and M-19 demobilized into the Democratic Alliance M-19 in 1990—about 13 years later, not 17.

Full reasoning

This sentence misstates the chronology.

  • Gustavo Petro was born on April 19, 1960 and joined M-19 at age 17, which places his entry into the group around 1977.
  • Reputable reference works state that M-19 demobilized in 1990 and became the legal political party Alianza Democrática M-19 that same year.

That means the transformation happened roughly 13 years after Petro joined, not 17 years later.

Claim
After the peace process between the Colombian government and the M-19, he was released
Correction

This reverses the sequence of events. Petro was released in 1987, before the 1990 peace agreement and demobilization of M-19, and then helped promote the peace talks.

Full reasoning

The article places Petro’s release after the peace process, but major reference works place it before the final peace agreement.

  • Britannica states Petro was arrested in October 1985 and released in March 1987.
  • The same source says that after his release, he helped promote peace talks between M-19 and the government.
  • M-19 then demobilized in 1990 after negotiations with the Colombian government.

So Petro was not released after the peace process; he was released years earlier and later participated in the push toward that process.
