After a middle school teacher in Fort Worth, Texas, was arrested in the shooting deaths of two neighbors, the mother of one of his alleged victims spoke out about the “almost random” killings.

“Our sons were defenseless and unarmed,” Paige Hudson Garcia wrote on Facebook on Tuesday. Garcia is reportedly the mother of Phillip Evans, who along with Daniel Haros was shot and killed on Oct. 23.

Police allege that Gary Heath, a local middle school science teacher, was responsible for their deaths, and he was arrested on murder charges the following Monday — after teaching a full day of class.

In her Facebook post, Garcia wrote that the victims were unconnected to the suspect, alleging, “The murderer did not know our sons, the shooting was completely senseless (almost random) but he is NOT remorseful.”

She added that the victims were in their pajamas in the front yard of their home when they were killed — “truly innocent victims by all accounts, in every sense of the word.”

Heath has not been cooperating with investigators, who still have not determined a motive, Fort Worth police tell PEOPLE. He remains in jail, according to records.

It is unclear whether Heath has entered a plea, and PEOPLE was not immediately able to reach his attorney — or the victims’ families — for comment.

Police say that Evans and Haros were killed soon after they attended a neighborhood Halloween party about the same time as Heath did, according to an arrest warrant previously obtained by PEOPLE. Heath was allegedly seen striking one of the victims with the butt of his rifle and allegedly confessed to his wife, according to the police documents.

Haros and Evans died from gunshot wounds and blunt force trauma to the face and head, according to the county medical examiner.

In a statement, the school district where Heath worked said he has been placed on administrative leave. According to his now-removed biography on his school’s website, he worked as an eighth-grade science teacher who once served in the U.S. Air Force.
