Senseney said a secure evidence room needs more than a lock on the door.
"People can go through drywall, ceiling tiles. You can't just rely on a steel door," he said. "We can't allow people to go in and steal drugs or firearms or other evidence."
The sheriff requested $614,000 from the county, up from $570,600 for this fiscal year.
Senseney's presentation led to a brief debate with County Commissioner James G. Knode over the role of the sheriff's department.
Knode said the sheriff's department should provide courthouse security, serve court papers and investigate bad check complaints.
Knode said other law enforcement efforts should be provided by West Virginia State Police. He said the county is paying for law enforcement that the state should be funding
There is not enough office space for the 12 sheriff's deputies, so Senseney asked the commissioners to rent additional office space for the deputies.
Jefferson County Prosecuting Attorney Michael Thompson requested $509,000 from the county commissioners, a $60,000 increase over this fiscal year.
Thompson said he wants to move three of his assistant prosecutors from part-time to full-time status to handle the increase in criminal court cases.
Thompson has five part-time assistants.
He said in addition to the criminal work, the attorneys in his office provide legal counsel to the county commissioners, the planning department, the development authority and the county assessor.
