A Carol Stream woman pleaded guilty Friday to shooting a Glendale Heights police detective during a lover's quarrel involving the officer's identical twin sister.
Maureen Manos, 49, shot Detective Jennifer Marcellis in the right arm early Jan. 30, 2010, after the victim returned to her Wayne home and found the defendant with her sister, who also lived there. An argument ensued and Manos was told to leave, a prosecutor said in court.

"When Jennifer turned her back and walked away, she was shot," Assistant State's Attorney Jim Scaliatine said.
An investigation by the DuPage County Major Crimes Task Force later cleared the victim and her sister Janelle -- also a Glendale Heights officer at the time -- of any wrongdoing in the off-duty shooting.
Authorities said Jennifer Marcellis dated Manos for several years but they broke up sometime before the altercation. Both sisters, then 31, listed the defendant as their girlfriend in court records.
Scaliatine said Manos gave varying details about the events leading up to the shooting but ultimately admitted she took a gun to the twins' home and loaded it when she arrived.
The injured officer required surgery but was able to return to work. Janelle Marcellis, a 10-year officer, resigned in June 2010 while facing an unrelated driving under the influence charge, to which she pleaded guilty last October, according to court records.
Manos, who claimed the gun went off accidentally, pleaded guilty to reckless discharge of a firearm and was sentenced to two years of probation and 30 days in the Sheriff's Work Alternative Program.
She had no prior criminal history, her attorney said.
"This was the appropriate sentence considering all the facts involved in this very complicated case," defense attorney Tim Martin said.
Scaliatine told Judge Robert Kleeman that prosecutors consulted the victim and police about Manos' negotiated plea.
"All were in agreement with the disposition," he said.
Manos also must receive counseling, pay court costs and fines, and is not allowed to possess guns as a result of her plea, prosecutors said.
