Police: Giron stole credit cards, confessed to murder of Jamis co-worker

Published October 28, 2021

NORTHVALE, N.J. (BRAIN) — Police investigators say Christian Giron used a hand-held sledgehammer to kill his Jamis Bicycles co-worker Jeanette Willem at the brand's headquarters Wednesday morning.

They say he then stole Willem's credit cards as well as a company credit card, drove home and changed his clothes and then returned to the office where he called 911. They say he confessed to the crimes at the Northvale police department soon after.

According to a police report, video surveillance cameras showed Giron approaching Willem at the office at about 7:39 a.m. The report redacts sections that appear to describe the exact interaction between the two. It says Giron discarded the credit cards in a garbage can along the street and hid the hammer under a parked trailer in front of the business.

The report says after returning to the office, which is about 2.5 miles from his home, Giron called 911 at about 8:15 and identified himself and said he had found an injured woman inside the business. 

Police said they later executed a search warrant on Giron's home and found a Jamis credit card and the clothes he was wearing during the attack there. They also located the garbage can and found Willem's credit cards and a pair of black gloves in it. 

Giron was arrested Wednesday on charges of first-degree murder, weapon possession, and hindering his own arrest, and was being held in county jail prior to his first court appearance. 

Willem, who worked at G. Joannou Cycle Co. for about 20 years, is being remembered fondly by retailers and those who worked with her.
