YUMA, Ariz. – Markley Allen Foster appeared in Yuma Superior Court for the second day of his trial. He is accused of killing a San Luis couple in a tragic crash that happened in May 2014 at the intersection of Highway 95 and Avenue 7E. Police say he went through a red light speeding and under the influence of drugs. He has been charged with several felonies including two counts of second degree murder.
In court on Tuesday the state called Natalie Ludwig, who works at the Arizona Department of Public Safety crimelab in Phoenix. She did tests on blood samples taken from Foster. In court she testified that traces of marijuana in the blood can have direct effects to a persons brain and can impair a person’s motor skills. She testified that Foster’s blood sample tested positive for traces of THC, a chemical compound found in marijuana. In cross-examination the defense tried to acknowledge that the effects she testified about were just generalizations and not specifically about Foster and how he may have or not have been affected in that way.
The state also called two employees of Yuma Regional Medical Center and questioned them about the way the blood was drawn and how it was cared for to the point it was sent to the crime lab. Due to veterans day the trial will continue on Thursday morning.
