Matthew Taylor Coleman, a California surf instructor and QAnon follower accused of killing his two young children with a spearfishing gun in Mexico, remains incompetent to stand trial and “rambles” incoherently behind bars, according to a new report.
The New York Post reports that the 43-year-old is “nearly incomprehensible” ahead of a looming deadline next week for him to stand trial.
Attorneys for Coleman only have until Feb. 18 to agree to a treatment plan for the QAnon follower, per court documents reviewed by PEOPLE. U.S. District Judge Cathy Ann Bencivengo ordered on Dec. 10, 2024, that no further extensions will be granted after Coleman’s attorneys repeatedly asked the court to extend its deadline for the defense to submit its response to the Bureau of Prison’s (BOP) treatment plan.
The court previously extended the deadline to Dec. 18, before extending it again to Feb. 18 after a request submitted by Coleman’s attorneys late last year.
The “proposed treatment plan to restore Mr. Coleman’s competence” was submitted to the court in September 2024, per the documents.
PEOPLE previously reported in October 2023 that Coleman had been deemed incompetent to stand trial. On Oct. 11, 2023, Bencivengo ordered Coleman to be committed for treatment and a competency hearing was scheduled for March 8, 2024.
Coleman is accused of killing 2-year-old son Kaleo and 10-month-old daughter Roxy on Aug. 9, 2021, in Mexico. He has pleaded not guilty.
According to charging documents previously reviewed by PEOPLE, he allegedly told police he was motivated by the conspiracy theories of QAnon and believed that his kids had “serpent DNA” and needed to be killed to save the world.
Authorities said Coleman drove from his Santa Barbara home with his kids into Mexico on Aug. 7, 2021, and allegedly killed them with a spearfishing gun on a ranch two days later. Police said Coleman then returned to his hotel and a farmer discovered the young children’s bodies in a remote part of the ranch in Baja California just hours later.
Coleman was arrested when he attempted to cross the border back into the U.S. and after his wife Abby called police to report her husband and kids missing, PEOPLE previously reported.
Coleman was indicted by a federal grand jury in September 2021 and has undergone psychological testing to determine his state of mind. In February 2023, federal prosecutors decided not to pursue the death penalty, according to an online docket entry previously reviewed by PEOPLE.
Attorneys for Coleman did not immediately respond to PEOPLE’s request for comment on Feb. 6.
