A 20-year-old man, identified in court records as the suspect in the May 29 homicide of a gas station clerk in Waukesha, was on probation for a burglary conviction in Milwaukee County.

Billy Ingram, a Waukesha man who lived with his cousin at 417 Jackson Court, is in the Waukesha County Jail pending possible criminal charges in the death of 56-year-old Nayyer Rana.

Rana was shot in the shoulder and the abdomen, as well as what appeared to be in the mouth. Two .40 caliber shell casings were located by a freezer and by the front entrance, the search warrant shows.

Ingram, who had a warrant out for his arrest, was taken into custody by Brookfield police during a burglary investigation. Ingram had Rana’s cell phone on his person, as well as various currency that appeared to have blood stains, according to the search warrant.

The Waukesha Police Department did not have any suspects on May 29 and Rana's family had offered a reward for information leading to the suspect's arrest.

Police located a loaded handgun, ammunition and clothing that appeared to have blood stains on it at the Jackson Court residence, according to the search warrant affidavit.

Police also are checking DNA evidence from Ingram as a long, black strand of hair was found on a shelf above Rana’s body, the search warrant states.

Police said last week that robbery was a possible motivation to the homicide. The gas station owner, Shabaz Qureshi, told investigators that $985 was missing from the store, according to the search warrant.

Other items that were stolen from the convenience store included cigarettes, smoking pipes, Hostess snack cakes and various cigars. Rana’s cell phone was missing, as well as his keys that were on a University of Wisconsin lanyard.

Early on the morning of May 30, Elm Grove police located a duffle bag and a backpack at a bus stop on Bluemound Road. The bags contained numerous packs of cigarettes, cigars and a laptop computer.

Less than a half-hour later, Brookfield police were searching for a suspect in a home invasion burglary when they saw Ingram at Bluemound and Sunnyslope Roads, the court filing states.

While questioning him, an Elm Grove officer approached and asked if he was missing some bags.

Ingram said one of the bags found at the bus stop was his, but he denied ownership of the second bag which contained Rana’s keys, unopened cigarettes and cigars, smoking pipes, the computer and $100.30 in cash, according to the affidavit.

Police said both bags had information linked to Ingram. Brookfield police were suspicious and contacted Waukesha police to share information, which led to Brookfield arresting Ingram.

Brookfield Police Capt. Jim Adlam credited the three departments for their cooperation.

"It was Waukesha, Brookfield and Elm Grove working together, and it was some great work by some young officers who thought it was suspicious, starting talking about it, thinking about it and taking steps to follow up," he said.
