Day Five, Part Two - FBI, USMC, And CSI

FBI Special Agent Kevin Boles was the first witness of the day as the prosecution continued its case-in-chief. Boles is part of the FBI's Cellular Analysis Survey Team, or CAST. Boles testified about the location of both Erin Corwin's cell phone and Chris Lee's cell phone on June 28, 2014 - the day Erin went missing. Some key findings:

• By comparing Erin and Chris Lee's respective phone records, Boles surmised both were traveling in an easterly direction from the Twentynine Palms Marine Base around 7:30 the morning of June 28.
• At roughly 7:36 a.m., Chris Lee's phone was in the same location where Erin Corwin's Toyota Corolla was later found abandoned.
• The last activity of any kind on Erin's phone was at 8:04 a.m. on June 28.
• The last activity on Chris Lee's phone was at 8:22 a.m. until 3:13 p.m. that same day.

The second witness to testify was a Marine veteran named Andrew Johnson, who currently works as a Shipfitter at Puget Sound Naval Shipyard in Washington state. Johnson was in the Marine Corps from 2010 until 2016. He was based at Twentynine Palms and was in the same Company as Chris Lee.

Johnson testified he approached the San Bernardino Sheriff's Department in July 2014 after learning of Erin Corwin's disappearance. Johnson said he told the Homicide Detail about a conversation he had with Chris Lee before Erin Corwin went missing. According to Johnson:

• Chris Lee asked Johnson about ways to hide or get rid of a body.
• Lee specifically wanted to know about the salt evaporation channels in Amboy, and whether a body could be submerged in the chloride pits.
• When Johnson asked Lee, "Who do you want to kill?" Johnson said Lee responded, "Don't worry about it," and gave him a "strange smile."
• Johnson testified he saw Lee make a list on in a notepad with two columns. One had "tools" with things like a shovel and chemicals, possibly lye. The other column had a list with the price of those items.

The third witness of the day was a Crime Scene Specialist with the San Bernardino Sheriff's Department named Susan Jaquez. She told the jury about the items of evidence she processed for fingerprints and DNA. Most of these items have been discussed on this blog before, including the items recovered from the same mine where Erin's body was found; Jaquez mentioned the tire, the two water cans which contained traces of gasoline, the propane tank, the homemade torch, and the Sprite bottle.

Jaquez also talked about twine she recovered from Chris Lee's Jeep. Both the prosecution and defense stipulated that an FBI analyst determined the twine from Lee's Jeep and the twine from the homemade torch were of the same "color, construction, and composition" and likely from the same source.

Both sides also stipulated that on Aug. 17, 2014 a member of the Anchorage Police Department pulled over a Chevy Suburban driven by Chris Lee, with wife Nichole Lee in the passenger seat.

The final witness of the day was Detective Woods, who was recalled to discuss the search warrant he served to examine the Suburban in Anchorage. Woods recovered several items of note, including two spools of paracord, knives, and blue climbing rope.

But the most important discovery was a garrote situated underneath the front passenger seat. (Because we all keep homemade garrotes in our vehicles, right?) The garrote was made with two pieces of white plastic, braided paracord, and black electrical tape.

That's it for today. Bedtime. Court resumes tomorrow at 10 a.m.
