WICHITA, Kan. (KSNW) – A Wichita father is facing criminal charges after his 3-year-old daughter allegedly shot and killed her 1-year-old sister inside their home, according to court records filed in Sedgwick County District Court, detailing the events leading up to the incident.

Michael Tejeda, 25, was arrested in connection with the Feb. 28 incident, in which his toddler daughter reportedly accessed his unsecured firearm and fired a fatal shot at her younger sister. Authorities responded to the scene after Tejeda called 911, frantically asking his daughter why she had pulled the trigger.

The child’s mother was not home at the time. She told police she received a FaceTime call from Tejeda, who informed her of the shooting. Upon arriving at the scene, she comforted her 3-year-old daughter, who repeatedly apologized.

A forensic examination determined that the fatal gunshot was fired from an intermediate range of one to three feet. Investigators found the firearm in Tejeda’s bedroom after he allegedly moved it following the shooting.

A background check revealed Tejeda had a prior felony conviction for drug-related charges and was still under court supervision at the time of the incident.

Tejeda has been charged with first-degree murder in connection with the shooting, two counts of aggravated endangering of a child, and criminal possession of a weapon by a felon. He remains jailed on a $500,000 bond.
