4:55 a.m.: Brian Walshe searches on his son's iPad, "How long before a body starts to smell?" He then proceeds to make several other internet searches about how to dispose of bodies over the next several hours.

6-6:10 a.m.: Brian Walshe told police that this is when his wife left home to catch an Uber or Lyft to the airport, to fly to Washington, DC for work. Prosecutors say no Ubers or Lyfts showed up at the home during this time frame. And though Ana Walshe did have a flight to DC, it was scheduled for January 3, and she never boarded.

1:21 p.m.: Brian Walshe searches "Is it better to throw crime scene clothes away or wash them?"

3 p.m.: Brian Walshe told police he traveled to his mother's house in Swampscott this day, before visiting Whole Foods and CVS. Surveillance footage doesn't show him going to either store.

12:45 p.m. - 1:14 p.m.: Brian Walshe searches whether a hacksaw is the "best tool to dismember" and whether someone can be charged with murder if there's no body. He also searches "Can you identify a body with broken teeth?"

Following the Google searches, Brian Walshe was seen on surveillance at the Home Depot in Rockland, where he proceeded to buy $450 worth of cleaning supplies with cash. Items in his cart, which he pushed while wearing gloves and wearing a face mask, included mops, brushes, tape, a Tyvek suit with boot covers, buckets, goggles, baking soda, and a hatchet.

4:27 p.m.: Surveillance shows Brian Walshe at an apartment complex in Abington, where he disposed of a garbage bag in the complex's dumpster. Prosecutors said it appeared the bag was heavy because Brian Walshe was leaning as he carried it and he had to "heft it" into the dumpster.

5:10 p.m.: Cellphone data shows him at another apartment complex in Brockton, again discarding items in a dumpster, according to surveillance video. The discarded items at these three locations were incinerated by the time investigators got to them.
