An Irving man was in custody Thursday after he was accused of killing his girlfriend's infant daughter.
Ruperto Florencio, 31, was being held at the Irving jail after his arrest on Wednesday, said Officer David Tull, an irving police spokesman.
He is suspected in the death of 7-month-old Giselle Gallegos, who died of internal injuries Tuesday at Children's Medical Center in Dallas.
Florencio was arraigned Thursday morning on the capital murder charge, and he was being held without bond, Tull said.
Investigators said they learned that the child’s mother, Maria Gallegos, went shopping Tuesday and that Florencio, her live-in boyfriend, stayed to care for the baby at their apartment on North Nursery Road in southeast Irving.
Florencio, not the baby's father, called Gallegos later, "telling her that Giselle was sick and that she needed to come home," Tull said in a news release.
"All three went to Baylor Hospital (Irving) where doctors began emergency care and contacted Children’s Medical Center for immediate transfer," Tull said in a statement. "Shortly after arriving at Children's, Giselle was pronounced dead."
Investigators reported that the girl died of internal injuries "not considered to be from an accidental cause," Tull said.
Florencio was also being held on charges of driving with an expired driver's license and failure to maintain automobile insurance.
Bonds for those charges were set at $205 and $375, respectively, although he was denied bond on the capital murder charge.
Also, jail records showed that a "hold" was placed on him by U.S. Immigration and Customs Enforcement.
Child Protective Services is also investigating the death, said Chris Van Deusen, a CPS spokesman in Austin.
He added, however, that there are no other children involved and the agency has not had previous contact with Florencio and the baby's mother.
