I think it would be standard procedure for law enforcement to subpoena all records such as credit cards, bank statements, cell phone records, computer records, etc., for an approved time period for the person who was the main focus of their investigation. I'm not saying at that point in time they would have had the right to go back five or ten years, but certainly for at least 30 days. In my opinion.
Snipped quote: Last week KGW reported that investigators have been using Terri Horman's cell phone and email records to see who she was in contact with just before and after the disappearance of Kyron.
Kyron's parents said they expected 'heavy' obligations for police this week in Kyron Horman case.

And from the following statement from Kaine, it seems he felt her spending habits were excessive:
Snipped quote: "Controlling with my money — yeah," Kaine said, "because she was spending all of it. She was going out and spending it like water and not checking with me where we should be spending our money."
The missing boy's stepmother, focus of the inquiry into his disappearance, is described as a giver and a taker, caring but controlling, sweet but manipulative.

And, strictly, in my own opinion only, the following suggests to me that at some point in time they received enough evidence of her involvement in Kyron's disappearance to investigate every dirty little secret she ever thought she hid:

Detectives in Roseburg are investigating allegations of a murder-for-hire plot involving Terri Horman that occurred nearly 30 years ago – long before her stepson Kyron Horman disappeared.

This would certainly have given them the right:
Snipped quote: Kaine Horman says he's learned from law enforcement officials that more than one circuit judge had found probable cause exists to implicate his estranged wife in Kyron's disappearance and in a murder-for-hire plot.
"I believe that Respondent is severely emotionally disturbed and unfit to parent Kiara. Her actions are horrifying and unexplainable,'' Kaine Horman wrote. "Kiara's physical and emotional safety are now at extreme risk.''
