María José Reyes Moore and Juan René Duarte Becerra were murdered in July 2012 in an antique shop in Lolol, Colchagua Province, O'Higgins Region, Chile.

Most accounts say that on 10 July 2012 Juan Duarte visited Óscar López's antique shop "to purchase an iron stick".

[2][3] Carabineros de Chile, the Chilean military police, stated that López stabbed Duarte in the back and subsequently beheaded him.

[4] López kept Duarte's head in a coffer, which was up for sale in his antique shop, and buried the rest of his body under rocks in his backyard.

[5] On 12 July, María José Reyes Moore was traveling with two of her children, her 15-year-old daughter and 19-year-old son, to Fundo Querelena in the Bucarruca area in the commune of Paredones, Cardenal Caro Province.

López then rushed towards the policeman with the bloody ax he had used to decapitate Reyes Moore, forcing González to shoot him with his service weapon, killing him.

[4] López began collecting phonographs, lamps, cart wheels and iron gates in 1997, when he moved to Los Boldos, a rural area near Santa Cruz.

[4] In an article published in regional newspaper El Mundo Rural in April 2012, López Rodríguez was described as a "modest man, who has worked hard with the shovel and the plow in the countryside," but "[his life] is devoted to visiting houses and rescuing antiquities which he repairs and sells to wealthy families."

"[22] Shortly afterwards, she began working at Colegio El Golf in Vitacura, where she created a class called La Academia (The Academy).

La Academia consisted of a pre-employment and functional workshop dedicated to high school graduates with special educational needs (necesidades educacionales especiales).

[26] He was the uncle of councillor (concejal) of the Lolol town hall Leandro Duarte Maldonado, from the Social Democrat Radical Party.

'Carabineers' Laboratory of Criminology') inspected the crime scene, under the request of public prosecutor Carmen Gloria Agurto, finding the decapitated body of another victim, later identified as Juan Duarte Becerra.

[30] O'Higgins Region public prosecutor Luis Toledo announced the Ministerio Público would give psychological assistance to Reyes' children, as they witnessed the crime.

The public prosecutor office of Santa Cruz requested the OS-9 (Departamento Investigación de Organizaciones Criminales; Department of Investigation of Criminal Organizations) to prepare a "psychological autopsy", as not much was known as to why López committed the crime, creating a profile based on interviews with people who interacted with him, and information extracted from the crime scene.

[3][31] The results of the "psychological autopsy" were made public on 25 July 2012, and pointed out that López Rodríguez "suffered of transitory psychosis, mystical delusions and bizarre behaviours.

[33] On 13 July 2012, at around 09:00 local time (13:00 UTC), relatives of María José Reyes arrived at the Servicio Médico Legal (Legal Medical Service) of San Fernando, where an autopsy was done, and took her body to Vitacura, Santiago Metropolitan Region,[3] where a wake over her body was held at Parroquia San Juan de Apóstol.

[7] A mass commanded by priest Osvaldo Fernández was held on 14 July 2012 at the Parroquia San Juan de Apóstol, attended by about one thousand people.
