OKC Police Investigate Possible Hazmat Situations

Oklahoma City police are responding to two possible hazmat situations Friday afternoon.

Police say two of their patrol cars used to hold and transport a murder-for-hire suspect Thursday may have been contaminated with hazardous materials. One police car is at a Valero gas station near Main and Penn. Authorities shut down Main Street in the area at about 12:30 p.m. Friday as they investigate. They cleared the scene at about 2:30 p.m.

The other police car is at an officer's home at Santa Fe and Indian Hills near Norman. Investigators remain on scene checking for contamination.

Four officers involved in the incident have been transported to the OU Medical Center for routine decontamination.

On Thursday, Oklahoma City police and the FBI went to 30-year-old Preston Rhoads' house to serve a warrant, and called the hazmat team out once they got inside. Police say someone tipped them off about Rhoads and now they're investigating him for solicitation of murder.

Investigators took numerous yellow bags full of items out of Rhoads' home in northwest Oklahoma City. Authorities will only say they're clearing the home of weapons and dangerous materials.

Police have not said what those dangerous materials are. However, Friday afternoon, officers are concerned that two of their vehicles may have been contaminated. Rhoads was held in one police car, and transported in the other one.
