Former Eagles cornerback Jack Ikegwuonu and his twin brother William confessed to a series of crimes, including armed robbery, in Madison, Wis., according to the Wisconsin State Journal.
The newspaper said that the brothers confessed, according to a search warrant filed Monday.
The Ikegwuonu brothers were arrested and charged last week for armed robbery, according to the city of Madison's website.
Ikegwuonu was a fourth-round pick by the Eagles (131st overall) in 2008 after playing at Wisconsin. He sat out the 2008 season with a knee injury. He was on the practice squad in 2009 and played in one game, a 24-20 victory over the Bears in November. He was released 2 days later and never played in the NFL again.
Ikegwuonu, 28, and his brother allegedly robbed Klinke Cleaners in Madison. The Madison Police Department, working with the neighboring Middleton (Wis.) Police Department, identified the brothers as suspects in four other holdups in Madison and Middleton between Nov. 13 and 21. The police said additional charges are likely.
