Police found a mother dead after she failed to pick up her kids. They just arrested her suspected killer.

A man has been arrested after he allegedly confessed to his family that he killed a mom, who was later found stuffed in a toolbox.

Francisco Javier Garcia Ventura was charged with murder this week after a medical examiner positively identified the remains of Crystal Garcia, 32, and said her death was a homicide, according to KSAT.

Garcia was a mother of four and police did a welfare check at her apartment when she failed to pick up her twin daughters, KSAT reported.

Garcia’s body was found last week inside a plastic toolbox in Comal County, Texas, according to KSAT.

Garcia Ventura was initially charged with tampering with evidence in connection with Garcia’s disappearance and arrested on Sept. 18 at a bus station, KSAT reported.

Garcia Ventura’s family called the police after taking him to the bus stop, KSAT reported.

They told police that Garcia Ventura “confessed to them of beating (Garcia) to the point that she stopped breathing” before taking her body to San Marcos, according to KSAT. He then asked them for a ride to the bus.

Police got a search warrant for Garcia Ventura’s apartment and found blood splatter on the bedroom wall and on “a security camera that was affixed to a kitchen wall that has been torn off,” according to the affidavit obtained by KSAT.

Investigators examined the apartment with a chemical designed to “reveal blood stains that have been washed out, wiped off, or are invisible to the naked eye,” according to the affidavit. The test confirmed “a heavy presence of human blood” in the apartment, KSAT reported.

Officers also reviewed CCTV surveillance, which showed Garcia Ventura leaving with a heavy-duty garbage bag, according to KSAT.

Garcia Ventura did not cooperate with investigators when he was taken into custody and asked for an attorney, KSAT reported.

Garcia’s bail has been set at $350,000, according to KSAT.
