A Texas man accused of fatally shooting his wife and kidnapping their toddler son on Sunday  has died from self-inflicting gunshot wounds.

ABC13 reports that 37-year-old Richard Concepcion, according to police, shot and killed his 32-year-old estranged wife, Sarah Alexis Furey, of San Antonio, before fleeing with their with their 18-month-old boy, Aaron. Police later found the toddler safe in the back seat of Concepcion’s truck in Guadalupe County, on the side of the road, on Sunday afternoon.

Authorities then tracked the suspect down and found him in critical condition after reportedly shooting himself. He later passed away at a local hospital.

During a news conference on Sunday, Police Chief William McManus said that the incident happened during a custody exchange between Furey and Concepcion. Numerous calls came in regarding gunshots coming from Furey’s home, off of Arbor Bluff in San Antonio. When police arrived, they found her dead at her doorstep. The couple had apparently separated around three months prior and according to McManus, were dealing with “custody issues.”

The couple had two other children together who were unharmed and not involved in the incident. All three are said to now be with relatives.

Court records indicate that Furey filed for divorce in Oct. and was granted a temporary restraining order against Concepcion during the same month.
