Cortez was initially identified as a person of interest in the homicide investigation and was detained in Alton on Thursday. His son, Robert Pena, barricaded himself in an apartment on the 1200 block of Harrison Avenue in Alton when police attempted to question him, according to Edinburg police Lt. Reynaldo Sepulveda. 

Pena died of a self-inflicted gunshot wound, police said.

At a Thursday press conference, police said Pena was in a relationship with Zamora.

"The father assisted the son in the murder," Sepulveda said.

A judge set Cortez's bond at $1 million. 

Cortez has requested a court-appointed attorney.
