Unsealed search warrant shows FBI was worried about IEDs, chemical warfare agents at west Lawton apartment

An FBI search warrant, which was unsealed earlier this month, has provided new information into an investigation of a west Lawton apartment in late January, including the discovery of a potentially deadly chemical warfare agent.

The FBI filed the search warrant on January 31. The warrant allowed agents to go inside the home of Philip Heath to collect evidence after numerous chemicals and components were found by Lawton police and the Oklahoma Highway Patrol Bomb Squad.

According to the warrant, when Lawton police went to the apartment on the morning of January 30 to serve a drug-related search warrant, they found detonating cord along with several unknown chemicals. Some of those chemicals had labels on them but several others did not. The FBI Special Agent who filed the warrant said some of the chemicals found in the apartment could have been used for creating improvised explosive devices. Investigators also said they found evidence that Heath had researched how to make explosive devices on the internet. No constructed devices were found inside the apartment.
