Trayvon Martin's family attorney says police should have tested George Zimmerman for drugs the night he shot the teenager.
Attorney Ben Crump told CNN's Piers Morgan that "what's really relevant is the fact there was no toxicology report done on George Zimmerman and we don't know what else was in his system with the prescribed medicines he was on to have him get out of his car in the rain, and profile, pursue, and confront Trayvon Martin and kill Trayvon Martin in cold blood, even though he was unarmed."
A fire and EMS report was released to the public Thursday, and it says Zimmerman was on the medications Librax and Temazepam.

WebMD says Librax is a combination of two drugs, one that reduces stomach cramping, and another drug that reduces anxiety. Temazepam, according to WebMD, is a sleep medication that is used for the short-term treatment for insomnia.
Dan Austin is a retired New York police detective and crime scene investigator, and the bulk of his work involved homicides, rape cases, and shootings. Austin says that just because Zimmerman admitted to taking medications doesn't mean that he was intoxicated, because millions of people take prescription medicine everyday.
"If the prosecutor was notified within several hours of the incident, I think the prosecutor or the state themselves should have absolutely made that decision, and told them look while you have him in custody and while we are trying to interpret this whole thing and interpret the law itself ask him if he would be willing to give a blood sample or urine sample, and if not I will get the subpoena or court order to say take him to a local hospital."
Martin was shot on February 26, and Austin says that if prosecutors wanted to learn about Zimmerman's drug use around the time of the shooting, they still have some options.
"It's not too late at this point to rule everything out. However, you have to understand there's only roughly a 90 day window. So the special prosecutor might want say look why don't we get a search warrant or subpoena to remove hair from Mr. Zimmerman from his head, which he has very short hair. So maybe they will want to get some pubic hair samples or hairs from his back that may be longer. They could send these hairs down for analysis to see if there's any trace evidence of illegal drugs in those hair samples."
