Global One (G1)— A gruesome scene at an apartment in Texas has led to the arrest of 27-year-old Junaid Hashim Mehmood.

Police arrived at the scene in response to welfare concerns Jan. 3 to discover 24-year-old Kimaria Nelson with a gunshot wound to her head and her three children dead.

According to court documents, a five-year-old, a two-year-old, and an infant were found with several wounds inflicted by a screwdriver and a hammer.

Mehmood’s brother reportedly called the police when he arrived to check on him and found large amounts of blood in the apartment.

Nelson was locked in the bathroom with several small pellets embedded in her head and face from an airsoft gun.

Mehmood was later picked up 25 miles from the apartment after calling to turn himself in.

He has reportedly admitted to stabbing the children.

Nelson is reportedly in stable condition in the hospital and a motive has not yet been determined.
