The former chief of security for the Hechinger Co. has been indicted by a Prince George's County grand jury on 26 charges of grand theft for allegedly obtaining checks from the company for business purposes, then using the money for personal expenses.

Kenneth Alfred Quigley, 50, of the 1700 block of Dryden Way in Crofton, turned himself in yesterday to county police. He was later released on his own recognizance.

The alleged thefts have been under investigation since February, when Quigley was asked to resign.

Quigley, according to the 18-page indictment, went to the Hechinger finance department 26 times between 1978 and February and asked for checks in amounts from $230 to $375. He then would cash the checks or deposit the money in one of several different Maryland financial institutions, according to the indictment. The indictment alleges that Quigley obtained between $5,980 and $9,750 from the company by that method.

Quigley, a retired D.C. police officer, had been head of security for the hardware and home improvement chain for 15 years, said Robert Tobin, a spokesman for the state's attorney's office in Prince George's County.

Hechinger officials asked the office of the state's attorney to investigate Quigley in April, Tobin said. A Hechinger spokesman declined to comment.
