The Hays Police Department search Sunday overnight to Monday of the single-family home at 329 W. 11th has resulted in two Hays residents being held on probable cause in the Ellis County Jail.


Shon Howard Mathwich, 41, and Amy Elizabeth Grove, 39, are being held in lieu of $30,000 bond each, according to Ellis County Attorney Tom Drees.


The two appeared on Tuesday by ZOOM before District Magistrate Judge Richard Flax.


Mathwich and Grove are each being held on one felony count of suspicion of criminal use of explosives posing a risk to the officer to defuse; and one misdemeanor possession of marijuana, Drees said.


Grove, who has a prior felony, Drees said, is also being held on suspicion of one felony count of criminal possession of a firearm by a convicted felon.


"Things could change," said Drees of the specific charges that might be filed. "This is still very, very preliminary."


The next step is for Drees to review the police affidavits and then file formal charges within the standard seven days allowed.


Kansas Highway Patrol’s hazardous device unit on Monday transported homemade explosive making material from the home, according to Hays Police Department Chief Don Scheibler.


HPD searched the home after being called there for a disturbance at the home on Sunday evening. At the house, the officers saw items in plain view that made them suspect drug related items in the house. Armed with a search warrant later, HPD officers searched the home and allegedly found some homemade explosives material, a marijuana growing operation and firearms, Scheibler said.


Evacuation of the neighborhood wasn’t necessary.
