An undercover investigation aired on Israel's Channel Two appears to show that the suspect in the tragic Jerusalem family poisoning, which left two infant girls dead and their brothers fighting for life, is still working as a pest exterminator.

The suspect, who cannot be named for legal reasons, is accused of having left an illegal, highly-toxic agent in the home of the Gross family, after completing an assignment there. He had stored the poison in the apartment's enclosed security room - also known as the "Mamad" or bomb shelter, which exist in most Israeli homes - but the security room's seal was less effective than the storage requirements for the chemical require, and the poison spread throughout the apartment over several days.

Four-year-old Avigail and two-year-old Yael died as a result, and their two brothers, Yitzhak and Michael, were left in critical condition. Rescue officials at the scene were shocked to discover that the chemical's toxicity was the highest level on the spectrum.

In a taped conversation, the reporter, who poses as a potential client, can be heard asking the suspect "I waited for you yesterday, I thought you'd call. I'm now in a hotel - when do you think you can come, if you have the time?"

The suspect responds "I can come in half an hour or an hour's time," apparently indicating his willingness to carry out the job.

In an interview with Channel Two, his lawyer admitted his client was banned by a court order from working with pesticides for 60 days, and denied the possibility that he could be currently engaged in pest control.

In a later conversation, the lawyer clarified that his client had never intended to actually carry out the assignment, but was going to pass it on to a colleague. He responded to the call in a professional capacity, he claimed, because he had not wanted the company to lose out on business.
