Police said a 9-year-old boy accidentally picked up the gun and shot the 18-year-old Jeremy Retana in the head, killing him.

“During the investigation, we learned a 21-year-old male, identified as Cristian Concha, had introduced a firearm to a 10 and 9-year-old who were at that residence visiting, allowed each one of them to handle it, and then, left it unattended and loaded while he intended to leave to go to QuikTrip. After he left the residence, the 9-year-old picked up the firearm and accidentally discharged it fatally injuring Jeremy Retana,” said Capt. Jason Stephens, Wichita Police Department.

Police said Concha’s girlfriend was babysitting the boys and left to go to QuikTrip.

“She was leaving with the suspect, the two children were left in the residence with the 18-year-old victim,” said Capt. Stephens.

Retana and Concha are cousins according to family KSN News spoke with.

Concha was booked in the Sedgwick County Jail on suspicion of felony murder and aggravated child endangerment.

“There is a statute known as felony murder which can be charged when an individual commits an underlying, inherently dangerous offense. In this case, this is aggravated child endangerment by allowing the children to have access to this firearm intentionally,” added Capt. Stephens.

The case will be presented to the Sedgwick County District Attorney’s Office.

The police department offered thoughts and prayers to those affected by the shooting.
