FLAGSTAFF, Ariz. (AP) \u2014 The attorney for a U.S. Air Force airman accused of killing a Mennonite woman grilled a ballistics expert who concluded that a bullet taken from the skull of the victim matched a rifle the airman owned.<\/p>\n\n\n\n

The cross-examination of Lisa Peloza, a firearms examiner with the Arizona Department of Public Safety, came before the prosecution rested its case. The defense then put on its own firearms expert who testified Thursday that he disagreed with Peloza\u2019s conclusion.<\/p>\n\n\n\n

Mark Gooch\u2019s attorney, Bruce Griffen, called just one other defense witness in the trial. Closing statements are scheduled Friday in Coconino County Superior Court.<\/p>\n\n\n\n

Gooch is accused of driving several hours from the metropolitan Phoenix air base where he was stationed to northwestern New Mexico, and kidnapping and killing Sasha Krause<\/a>. He faces life in prison if convicted of first-degree murder and other charges.<\/p>\n\n\n\n

Krause, 27, was gathering materials for Sunday school at the Mennonite community where she lived when she disappeared on Jan. 18, 2020. Her body was found more than a month later, face down with her hands bound by duct tape, on the outskirts of Flagstaff.<\/p>\n\n\n\n

A medical examiner determined she died from blunt force trauma and a gunshot wound to the back of the head.<\/p>\n\n\n\n

Griffen sought to undermine Peloza\u2019s credibility, pointing out that she reproduced a colleague\u2019s ballistics work in a high-profile case in Phoenix in 2015 that came under heavy scrutiny. Other ballistics experts came to different conclusions, and the case involving a string of freeway shootings was dismissed.<\/p>\n\n\n\n

In Gooch\u2019s case, Peloza testified that she found sufficient characteristics specific to Gooch\u2019s .22-caliber rifle and the bullet in Krause\u2019s skull to say that gun fired that bullet. She said it wasn\u2019t possible to demonstrate with visuals how she came to the conclusion, partly because of the quality of the photos taken from the microscope.<\/p>\n\n\n\n

The defense expert, Eric Warren, said he tried to reproduce Peloza\u2019s findings but did not see what she saw. His presentation to the jury included photos of the bullets he test-fired from the rifle, the test-fires done by Peloza and the bullet from Krause\u2019s skull.<\/p>\n\n\n\n

Warren said he could not conclusively link the firearm that Gooch owned to the bullet from Krause\u2019s skull.<\/p>\n\n\n\n

\u201cAt most, I could find one, two things that matched up. But it all appeared random in nature,\u201d he said.<\/p>\n\n\n\n

The firearms testimony was the most contentious of the trial that is on track to go to the jury Friday. Jurors in Arizona are among those in a few states that can ask questions to witnesses. On ballistics alone, the jury submitted about a dozen questions in writing to Brown Nichols, who read them aloud.<\/p>\n\n\n\n

One juror was dismissed Wednesday because of a family emergency, leaving two alternates.<\/p>\n\n\n\n

There\u2019s no indication Gooch and Krause knew each other. But both grew up in the Mennonite faith<\/a> \u2014 Gooch in Wisconsin and Krause in Texas. No eyewitnesses, DNA or fingerprints link Gooch to Krause\u2019s disappearance and death, making the case against him largely circumstantial.<\/p>\n\n\n\n

Authorities used cellphone data, financial records and video surveillance to determine Gooch\u2019s phone traveled to Farmington, New Mexico, the day Krause went missing and before heading back toward the air base with a detour to the area where Krause\u2019s body was found. Video at the base showed Gooch\u2019s car return early the next day.<\/p>\n\n\n\n

Prosecutors allege he tried to cover his tracks<\/a> by deleting Google location history, getting his car detailed and asking a friend to store a rifle.<\/p>\n\n\n\n

Gooch told a sheriff\u2019s detective he took a drive the day Krause disappeared because he had time and was seeking out Mennonite churches for fellowship, but his times don\u2019t match up with the records. He denied killing her.<\/p>\n\n\n\n

Gooch has been jailed in Coconino County since his arrest in April 2020. Reports from the sheriff\u2019s office show he has two disciplinary records, including a physical fight with an inmate that left him with a bloodied nose and black eye. The report doesn\u2019t detail what led up to it.<\/p>\n\n\n\n

Growing up, he worked on his family\u2019s farm in Wisconsin, attended a Mennonite school through the eighth grade, got his GED and joined the Air Force against his parents\u2019 wishes, his father, Jim Gooch testified Thursday. Mark Gooch never officially joined the church, his father said.<\/p>\n\n\n\n

\u201cTo the best of my knowledge, he wasn\u2019t of a converted heart,\u201d he said. \u201cAnd, at that point, I don\u2019t think he felt a need for it,\u201d Jim Gooch said.<\/p>\n","protected":false},"excerpt":{"rendered":"
