Police supervisor arrested, accused of several domestic violence crimes

A Wichita police supervisor was arrested early Tuesday on suspicion of domestic violence incidents spanning more than three years, Interim Police Chief Nelson Mosley said.

The supervisor, identified as Dwain Diehl, was booked on suspicion of seven offenses, Mosley said: two counts each of aggravated battery, criminal restraint and simple battery, and one count of aggravated assault.

Investigators were alerted Monday afternoon to the incidents, which reportedly occurred in Derby and rural Sedgwick County, Mosley said. Diehl was questioned and then booked into jail.

The case will be presented to the Sedgwick County District Attorney’s Office by sheriff’s investigators later this week, Mosley said.

Diehl, 47, has been with the department for 19 years. He has been suspended with pay.

“We hold our employees to a higher standard,” Mosley said. “Being ethical – that’s in our mission. We expect our officers to do the right thing.”

Diehl is the second Wichita police officer arrested on suspicion of domestic violence in less than a week. Branden Ryan Glass, 23, was jailed early Thursday morning on assault and battery allegations linked to events that happened at a party on New Year’s Eve and an incident or incidents that occurred between Aug. 1 and Aug. 10, according to police and court records.

Glass was charged Tuesday in Sedgwick County District Court with four counts of aggravated assault and one count of criminal threat – all felonies – and one count of battery. The criminal complaint filed against Glass accuses him of “unlawfully and knowingly” threatening four different people with “a deadly weapon” – a firearm – and of “unlawfully threaten(ing) to commit violence communicated with the intent to place another in fear” the same four people, both in August.

Glass was fired on Tuesday, said Wichita police spokesman James Espinoza.

In the misdemeanor battery count, Glass is accused of “unlawfully and knowingly” touching one of the victims “in a rude, insulting or angry manner” on Jan. 1.

Police have said Glass was arrested after police responding to a disturbance near 10th and St. Paul involving a domestic-violence incident at Glass’ home; while there, the officers learned of the alleged incident in August.

Glass was off duty at the time.

District Judge Joe Kisner set Glass’ preliminary hearing for Jan. 21. He is free on bond and has been ordered to have no contact with the alleged victims and “no contact with any firearms,” according to court records.

Mosley called the two arrests so close together “unfortunate.”

“Hopefully, the message is we do police our own,” he said.
