The operator of a janitorial service that cleaned the Alamodome has been convicted in an invoice scam that led to more than $500,000 in overcharges.

Federal investigators say 54-year-old Geoffrey Comstock was convicted Wednesday in San Antonio of conspiracy to commit wire fraud and six counts of wire fraud.

The case involves the Alamodome, a multipurpose domed sports and special events facility operated by the city of San Antonio.

Authorities say Comstock owns the Frio Nevado Corp. and had an Alamodome janitorial contract from 2002 to 2016. Investigators say bogus invoices, submitted since mid-2014, were paid by the city.

Comstock faces up to 20 years in federal prison on each count.
