A San Antonio police officer who was fired last year for dating a woman convicted of prostitution was investigated for possible criminal acts, including possession of child pornography and a possible illegal substance, according to records obtained by the San Antonio Express-News.

The documents, which describe interviews by internal affairs investigators with multiple official and unofficial sources, portray former Officer Mark Walaski as a man who used his job as a police officer to control his then-girlfriend, check on her whereabouts, and possibly try to thwart an investigation of his actions.

Walaski, who had been with the department for nearly 22 years, has appealed the firing, which was effective in June. His employment record shows an earlier suspension, for three days in April, for lesser infractions.

For the last three years, court records show, Walaski has been the caretaker for a different ex-girlfriend’s 17-year-old daughter, and she was living at his house at least as of last fall.

Contacted by investigators, Walaski’s girlfriend, the one who was busted for prostitution, told them that Walaski had watched through a hole in a wall in his house while the teenager showered. She also said he stored child pornography on his private computer and had a plastic bag of what could be an illegal powder.

Walaski denied the allegations during interviews with internal affairs investigators. When San Antonio Police Chief William McManus indefinitely suspended Walaski in June, these additional allegations were not cited as reasons for his termination. It is not clear why.

Walaski’s lawyer from CLEAT, a state police union, did not respond to a call seeking comment.
