SIOUX FALLS, S.D. (KELO) — A Sioux Falls police officer made his first court appearance on charges of child pornography.

According to jail logs, Matthew Jock, 23, was booked Wednesday afternoon for child pornography. On Thursday, a judge set bond for Matthew Jock at $25,000. He’s facing five felony counts of possession of child pornography, with each charge carrying a maximum sentence of 10 years in prison.

Sioux Falls Police Chief Jon Thum said Thursday morning Jock is no longer employed as a SFPD officer. Thum said he is “upset and troubled” like many in the police organization and in the community. 

He called it a “black eye” on the police force and added police will be reevaluating its safeguards for issues like this.

Sioux Falls Mayor Paul TenHaken said he is “deeply troubled” and “angry.” TenHaken said he still supports the officers in SFPD. TenHaken said his office and the SFPD will focus on regaining trust within the community.

According to court documents, the South Dakota Internet Crimes Against Children Task Force, part of the Division of Criminal Investigation, received a CyberTip from the National Center for MIssing and Exploited Children regarding a Kik Messenger user account with video files suspected of depicting child pornography.

Jock admitted to authorities he used the Kik Messenger account reported in the CyberTip.

Court documents say Jock had a video file of a juvenile female, who appeared to be 8-10 years old, performing oral sex on an adult man. Investigators tied the video file to Jock’s home in Lincoln County.

Lincoln County State’s Attorney Tom Wollman said Jock was arrested without incident. 

Wollman said the investigation is on-going and isn’t sure if more people will be arrested from the video files. 

Bond has not yet been addressed.

His initial court appearance is scheduled for 11:30 a.m. today in Lincoln County. 

This is the second SFPD officer to be arrested for child pornography. Luke John Schauer was arrested earlier this month.
