CHICAGO (AP) — Two men whose murder convictions were overturned and walked out of prison after spending more than 20 years behind bars are alleging in lawsuits that the same Chicago police detective helped frame them.

In federal lawsuits, Roberto Almodovar Jr. and Jose Maysonet allege that now-retired Detective Roberto Guevara beat them into false confessions and coerced witnesses against them.

Last April, Almodovar was freed after a judge dismissed charges against him in a 1994 double homicide. In November, Maysonet was set free when charges were dropped against him in a 1990 double homicide.

The lawsuits name other former Chicago police officers but the key player in both suits is Guevara — a former detective linked to at least nine convictions that have been tossed out in less than two years.
