We did obtain footage of Eric Arsno walking through the store and also Eric Arsno purchasing items.

We were able to identify the items that he purchased to be a chainsaw and trash bags.

Based on the items that Eric purchased at Home Depot and the surrounding events around Maria's disappearance,

it was concerning that Maria's body may have been disposed of.

It's after 9 a.m. at the Houston-Texas Legal Office, where 29-year-old Maria Jimenez Rodriguez has been a paralegal for over six years.

Maria is usually at her desk by now, getting an early start on the day, but she hasn't arrived yet.

Her coworker Brenda receives a text from Maria saying that she's running late, dropping off her daughter Destiny at the babysitter.

But by the end of the day, Maria still hasn't shown up for work.

And Destiny waits impatiently for her mother to pick her up.

I'm Steve French, and this is Unsolved Mysteries. Texts from a killer.

Early on the morning of June 21st, 2018, Brenda Lopez knows something is wrong.

Her coworker Maria Jimenez Rodriguez hasn't shown up for work.

The first message she texts was at 8.57 and that was to my boss and myself.

I said, good morning, I'm running late stuck in traffic.

She was supposed to be at work at 9 o'clock.

Our office policy is to text 30 minutes before you're going to run in late or something comes up.

That was weird because she'd always get here 15 or 20 minutes before 9 o'clock.

Brenda Lopez is one of Maria's closest friends, the law firm, where they both work.

We both started at the firm together. She was very hardworking, very outgoing.

Always a go-to person. Always try to help clients out, help the staff out, always pull together, whatever we need it.

She'd always come in early, make sure everything was going in the office, check messages,

and if she had to stay late to get the job done, she stayed late.
