SAN ANTONIO, TX (The Daily Mail) – An undocumented immigrant from Mexico has been arrested and charged with shooting a 15-year-old girl from Texas who was pregnant with the suspect’s second child at the time of her slaying.

Police in San Antonio say Jennifer Delgado was nine months pregnant when on Monday morning she was gunned down by Armando Rodrigo Garcia-Ramires, 35, who then tried to take his own life.

Investigators say the victim already had a one-year-old son with Garcia-Ramirez, who at one time had been her stepfather.

The suspect had been released on bond from the custody of the US Immigration and Customs Enforcement last May.

About a month later, according to investigators, Garcia-Ramires impregnated Delgado for a second time.

He now faces two charges of capital murder in the deaths of the teenager and her unborn baby.

The incident began unfolding at around 11am on Monday when police responded to the 1100 block of Babcock Road in San Antonio and found Garcia-Ramires suffering from a self-inflicted gunshot wound to his mouth, reported KSAT.

While working at the scene of the failed suicide attempt, officers learned that Garcia-Ramires may have committed a crime at another location nearby.

Police were then led by a witness to Jennifer Delgado’s home in the Spanish Keys Apartments in the 1150 block of Babcock Road, where they found her front door kicked in.

Upon entering, officers discovered the teenage expectant mother dead from multiple gunshot wounds to the head.

Delgado’s one-year-old son was also inside the home but was unharmed.

The slain woman was rushed to University Hospital in the hopes of saving her unborn baby, but the child was pronounced dead on arrival.

Garcia-Ramires was also transported to University Hospital to be treated for his injuries. He was later booked into the Bexar County Jail on $2million bond, and on Tuesday, ICE placed an immigration hold on him.

Records reviewed by the Houston Chronicle indicate that Armando Garcia-Ramires, a native of Mexico, was first picked up by ICE agents in January 2011 through the criminal alien program of San Antonio, and he was released on bond less than a month later.
