(Uncredited) (Newser) – One of the FBI's 10 Most Wanted Fugitives spent just 13 days on the infamous list before turning himself in. Edwin Ernesto Rivera Gracias, 28, voluntarily returned from El Salvador to Colorado yesterday to face a first-degree murder charge, the AP reports. The FBI had offered a $100,000 reward for information leading to his arrest in the 2011 slaying of Richard Limon, 69. As ABC Denver reports, the plot he was allegedly involved in reads like the script for a made-for-TV movie: At the time of the murder, Rivera Gracias was dating Nena Moya, then 17, the daughter of Limon's wife, Tina Moya. Nena told Rivera Gracias that Limon had molested her and sexually assaulted her mother. The arrest warrant affidavit states Rivera Gracias wanted to kill him over the allegations; Tina Moya had also asked various people to kill him. Ultimately, the affidavit states, she convinced Rivera Gracias and her boyfriend to do the deed while she and her daughter, aware of what was going on, were nearby. Rivera Gracias is accused of wielding the knife that killed Limon; his body was found dumped near a guardrail on Lookout Mountain with a steak knife blade stuck in his chest. Tina Moya and her boyfriend pleaded guilty to second-degree murder and were sentenced to 36 and 48 years, respectively; Nena pleaded guilty to being an accessory to murder and was handed a two-year sentence, to be served in a youth corrections facility.
