When jurors deliberate whether Jodi Arias is guilty of murder in the killing of her ex-boyfriend Travis Alexander, one of the toughest issues they will have to decide is whether his death was premeditated.

This week, Arias is expected to testify about the circumstances surrounding her road trip from Yreka, California, to Alexander's home in Mesa, Arizona.

Prosecutor Juan Martinez says Arias set out on the road trip June 2, 2008, intending to kill in premeditation.

In Session's legal experts put together information from testimony, phone records and court documents for a picture of Arias' actions in the days before and after Alexander's death.

June 2, 2008:

Yreka, California

Phone records show several calls between Arias and Alexander in the early morning hours:

Arias called Alexander four times between 1 a.m. and 3 a.m.

These calls were all very short, the longest 17 seconds.

Alexander called Arias twice during the 3 a.m. hour:

• The first call was just under 18 minutes, the second about 41 minutes.
• Arias called Travis at 4:03 a.m. The call lasted 2 minutes, 48 seconds.

At 5:39 a.m. Arias bought $15 worth of gas at Shell Food Mart in Siskiyou, California.

Redding, California

At 8:04 a.m., Arias rented a car at Budget Rent A Car. The rental agent testified Arias had blonde hair at the time. She refused the first car he offered her because it was red. Instead, she rented a white Ford Focus. She allegedly wanted a car that wouldn't stand out. She also told the rental agent she would be using the car locally. According to the rental agreement, the car was supposed to be returned on Friday, June 6, around 8 a.m.

June 3, 2008:

Monterey, California

Arias made three deposits to different accounts at a Washington Mutual branch:

• 10:10 a.m. $400 to account # ending 8006
• 10:11 a.m. $300 to account # ending 7148
• 10:15 a.m. $100 to account # ending 7148

Arias called Alexander twice:

• A 17-second call at 12:57 p.m.
• A 2-minute, 50-second call at 1:51 p.m.

Arias' ex-boyfriend, Darryl Brewer, testified Arias stopped by his house in Monterey, California, on June 3, 2008. Brewer said he gave Arias two gas cans, because she needed them for a long road trip. In Session's legal experts say this could be evidence of premeditation, because Arias may have been trying to cover her tracks, using the gas cans so she would not have to buy gas in Mesa, where Alexander lived.

Salinas, California

At 3:22 p.m., Arias goes shopping at a Wal-Mart and buys two facial cleansers and three unidentified items. The sale total was $43.90 and she paid cash.

Pasadena, California

At 8:16 p.m., Arias calls Alexander. The call lasted 2 minutes, 9 seconds.

At 8:31 p.m., Arias goes to a CVS pharmacy. It is not clear what she bought.

At 8:34 p.m., Arias calls Alexander again and the call lasts 49 seconds

Between 8:42 and 8:46 p.m., Arias makes two gas purchases at Arco. The first is for $34.61, and the second is a pre-paid purchase for $40.

She may have filed up her rental car and the gas tanks with fuel.

Ryan Burns testified Arias called him around 9 or 10 p.m. on June 3, 2008. She told him she was on her way to Utah. Burns expected her to arrive around 9 a.m. the next morning, Wednesday, June 4.

June 4, 2008, the day Alexander died:

Mesa, Arizona

Arias told police she arrived at Alexander's house at 4 a.m. She says Alexander was still up waiting for her and watching YouTube videos. The police search of Alexander's computer confirms it was in use at that time. Arias says Alexander wanted to have sex, but she was tired, so they went to bed.

At 1 p.m., Arias says she and Alexander woke up and had sex. They also took nude photos of each other in his bedroom. Later, she says, they had rough sex in his home office.

At 5:22 p.m., Arias began taking pictures of Alexander in the shower.

Investigators retrieved a total of 19 images from the camera.

Four of those photos tell the story of the last minutes of his life:

• 5:29 p.m. Arias snapped a photo of Alexander in his shower just minutes before he died.
• At 5:31 p.m. Arias defense attorney Jennifer Willmott says there was a photo taken accidently when Arias dropped the camera. This photo shows the ceiling of Alexander's bathroom.
• At 5:32 p.m. There is a picture of Alexander bleeding and on the ground, it's also possible to see what looks like Arias' leg and foot.
• At 5:33 p.m. There is a picture of blood on the baseboard.

At 10:30 p.m., Arias calls Burns to tell him she got lost but she's on her way and will be in Utah by the morning.

In the 11 p.m. hour, Arias calls Alexander's phone three times:

• The first call is at 11:37 p.m. and is 31 seconds long. 
• The second call is at 11:48 p.m. and she leaves a voicemail.
• The third call was at 11:53 p.m. It was 16 minutes long.

Investigators say Arias may have accessed Alexander's voicemail account on June 4. Phone records show Arias was between Kingman, Arizona, and the Nevada border when she made the calls.

JUNE 5, 2008:

West Jordan, Utah

Between 10 a.m. and 11 a.m, Burns says Arias arrived in West Jordan, about 700 miles from her starting point.

Ryan testified he noticed her hair was dark brown; her hair had been blonde when they met. He also notices cuts and bandages on her fingers. She tells him she cut her fingers at the Margaritaville restaurant where she worked. However, there is no Margaritaville in or near Yreka.

At noon, Burns and Arias go to a business meeting. She follows him there in her rental car. On the way, she's pulled over because her license plate is upside down, and the patrol officer gives her a warning. After the meeting, they go back to Burns' house, where they watch a movie and "make out."

At 7 p.m., Burns and Arias go to another business meeting. Again, they go in separate cars. After the meeting, Arias gives a friend, Leslie Udy, a ride to dinner. Udy says Arias seemed fine and that they talked about Arias' breakup with Alexander before joining Burns and his friends for dinner.

Around 11 p.m., Arias and Burns go back to his house. They take a nap and when they wake up, they begin making out again. Burns says their contact stopped short of all-out sexual activity. He also says she was much stronger than she looked. Arias left Burns' house sometime after midnight.

June 6, 2008:

Salt Lake City, Utah

Arias makes two gas purchases at Tesoro between 3:57 a.m. and 4:05 a.m. The first one was for $41.18. The second one was 8 minutes later for an additional $36.98.

Winnemucca, Nevada

Arias spends $49.91 on gas at a Flying J Travel Plaza. She also spends $4.90 on other items. There is no time stamp on the receipts for these purchases.

Sparks, Nevada

At 10:34 a.m., Arias buys gas at a 7-Eleven. It is not clear how much gas she bought. She also makes two purchases at an In-N-Out Burger at 10:38 and 10:43 a.m.

June 7, 2008:

Redding, California

At 12:20 p.m., Arias buys gas at a Valero.

At 1:08 p.m., Arias returns her rental car. She originally planned to return the car on Friday, June 6 at 8 a.m. Some time during the week, she apparently extended her rental until 9:30 a.m. Saturday, June 7. The rental agent testified that the car appeared to have "Kool-Aid" stains on the passenger seat and back seat and all the floor mats were gone.


In all, Arias traveled 2,834 miles.

She was arrested a little more than a month later, on July 15, 2008.
