— A Janesville man accused of selling heroin in March is a person of interest in a Nov. 12 shooting in Waukesha, according to a criminal complaint filed in Rock County Court.

The shooting victim, who was not injured, was a former police informant who had testified against Demetrius L. Cooper, 31, of 15 Elliott St., Janesville, and who had been scheduled to testify again this week, according to the complaint.

The former Janesville police informant called the department Nov. 12 and said somebody had shot at him outside his home in Waukesha County, according to the complaint. He reported the incident to the Waukesha County Sheriff's Office, and deputies collected shell casings from his yard.

The informant told Janesville police he suspected the shooting was connected with a Janesville drug case in which he was scheduled to testify, according to the complaint.

A second confidential informant, whose name is not listed on the complaint, told Janesville police Cooper had a gun Nov. 10 and rented a truck. The truck matched the description of one parked near the informant's home at the time of the shooting, according to the complaint.

A source not named in the complaint told police Nov. 20 that Cooper planned to kill the police informant as well as Eddie Matlouck, 43, of 15 Elliott St., Janesville. Matlouck was arrested on heroin charges alongside Cooper, according to the complaint.

Cooper was arrested Wednesday on four charges of felony bail jumping. He is accused of failing to update his address and violating bond conditions by committing a new crime, according to the complaint.

Cooper remains locked in the Rock County Jail on a $110,000 cash bond.

Capt. Karen Ruff with the Waukesha County Sheriff's Office declined to comment whether an arrest or charges were pending in the shooting.

Cooper was scheduled to appear in court again today on four counts of delivering heroin, four counts of maintaining a drug trafficking place and one count of felony bail jumping. He was arrested March 18 at Delavan Drive and Putnam Avenue in Janesville. In April, he posted a $15,000 cash bond, according to online court records.

The bond was amended Wednesday to $90,000. Bond in Friday's bail jumping case was set at $20,000, according to online court records.

In December 2010, Cooper was charged with substantial battery and released on a $500 signature bond. He is scheduled to appear in court Tuesday, Dec. 20, on that charge, according to online court records.
