Zimmerman's alibi challenged by FBI agent, cell tower tracking of suspect's car

Zimmerman's alibi challenged by FBI agent, cell tower tracking of suspect's car


BLOOMINGTON — Kirk Zimmerman’s alibi that he was home resting after a day of yard work around the time his ex-wife was killed in November 2014 was challenged in testimony Monday by an FBI agent.

Special Agent Greg Catey was the state’s final witness in Zimmerman’s murder trial on charges accusing him of shooting Pam Zimmerman.

Catey reviewed 37 pages of cell tower data during his three hours on the witness stand. In addition to Zimmerman’s travel on Nov. 3, 2014, the day his former wife was killed, Catey also reviewed cell tower records for Oct. 25, 2014, that show Zimmerman allegedly went to Crawfordsville, Ind., where the state claims he may have bought a gun.

The 9 mm gun used to kill the 53-year-old victim at her east Bloomington office was not recovered.

Looking at records showing communication between a device in the defendant’s car and cell towers, Catey testified Zimmerman’s car was not at home at 6:31 p.m. but was identified by a cell tower as being near the victim’s office at 2103 E. Washington St. in Bloomington.

It's possible Zimmerman’s vehicle had returned to his home on Park Ridge Road by 6:55 p.m., according to the report.

Zimmerman’s car also moved from his home around 10:28 p.m. and traveled to several east-side areas for about an hour, said Catey. The locations of the car’s path may have included an area near the victim’s office where several items from her purse and office were found the following day.

An area east of Central Illinois Regional Airport also was recorded by a cell tower during the later trip, said the witness.

In his statement to police after his ex-wife was found with four gunshot wounds, Zimmerman claimed he did not leave his home after completing yard work and a nap.

Zimmerman’s former girlfriend Kate Arthur has testified she went to Zimmerman’s home around 6:30 p.m. for a scheduled visit but he did not answer the door. He returned her call shortly after 7 p.m. and she went to his home for about two hours, she said.

On Oct. 25, 2014, the day after Zimmerman received a FedEx package from his ex-wife demanding $4,000 in past-due child support, he made the trip to Indiana, according to Catey’s report. The report shows Zimmerman turning around and returning after a brief stop in the Indiana town.

Jurors heard testimony last week from an expert on illegal gun sales who opined Indiana is a major source of such weapons that end up in Illinois.

The defense has argued Catey’s report is based on “junk science” and is unreliable.

In earlier testimony Monday, Bloomington police Detective Bill Lynn showed jurors analysis of Zimmerman's computer that found records of a search he conducted about 10 days before his ex-wife was shot. Lynn said Zimmerman searched the internet for information on how to disable tracking capabilities on his car.


Bloomington police Detective Bill Lynn described a Google search made by Kirk Zimmerman (fourth line) before an alleged trip to Indiana that asked whether one could suspend Sirius radio service during testimony Monday at the Law and Justice Center in Bloomington.

The timeline of activity from Zimmerman’s home computer showed a Google search for “Can I suspend Sirius?”

Police contend Zimmerman wanted to avoid the ability of authorities to trace his travel to Indiana.

The jury also saw three short surveillance videos of the parking lot of Pam Zimmerman's office building. The videos, taken by nearby State Farm cameras, show vehicles, including one the state claims is similar to the defendant’s 2013 silver Hyundai Sonata.

Lynn was not allowed to point out a specific image on the videos, but he confirmed the displays contained images of interest to police.

The first video showed a car with a sun roof, one feature of Zimmerman’s car, in the parking lot at 4:32 p.m. and remaining there for several minutes.

Portions of the video also show a car with a sun roof parked there at 4:37 p.m.

The state has argued that other silver vehicles also were in the area around the time the victim was killed.

First Assistant State's Attorney Brad Rigdon said the state expects to rest its case Tuesday morning. 

Defense lawyer John Rogers told Judge Scott Drazewski he will offer arguments in support of a directed verdict. That could end the trial if Rogers can convince the judge the state has failed to make its case.
