CHARLESTON, S.C. – A state crime scene investigator testified Tuesday that he was concerned when he examined the body of a black motorist shot by a white police officer, because what he saw didn’t jibe with what he was told about how Walter Scott died.

Almon Brown, an investigator for the State Law Enforcement Division at the time, testified that when he arrived at the scene of the April 2015 shooting, he was briefed that it happened during a confrontation between Scott and Michael Slager, a former North Charleston patrolman.

Scott’s wounds “seemed to be in the back and side and (that) didn’t seem to be correct,” Brown testified.

Slager could be sentenced to 30 years to life if convicted of murdering Scott as the motorist fled a traffic stop after being pulled over for a broken taillight. A bystander recorded the final encounter and the video has been seen millions of times.

Brown was called to present photos he took at the crime scene, including a photo of Scott’s body that was shown to the jury.

Another crime-scene expert who testified Tuesday was former North Charleston Police Department investigator Scott Wyant, who said he didn’t do a complete investigation at the scene because state investigators handle shootings involving police officers.

Wyant served more than 20 years with the department. He said on cross-examination that he was told by his superiors in the department not to do a trace-evidence investigation on Slager looking for such things as gunpowder residue. Wyant said he had expressed his concern that doing so would involve a conflict of interest.

Defence attorney Andy Savage has long questioned the adequacy of law enforcement’s investigation and at one point last year filed a motion asking the court to look into what he contended was the state’s destruction of evidence.
