Marie and Andrew Neumann, ages 22 and 53, respectively, were charged Tuesday with first-degree theft in King County Superior Court.
Prosecutors allege the pair of employees contracted with the company snuck into the Microsoft store on two occasions in January with the help of an unwitting security guard.
Marie Neumann also posted evidence on Facebook of possessing a doctored access key.
Furthermore, Andrew Neumann had an active protection order against his daughter, court records say.
Marie Neumann works in Microsoft's catering department and Andrew works as a shuttle driver, according to court documents. Neither position allows them to enter the software room of the company store, which is restricted to full-time employees with certain access keys.
The first time the pair is believed to have entered the software room was Jan. 14. Andrew Neumann's employee key card was denied twice at the entry, but a security guard used his card to open the turnstile for Andrew and his daughter.
King County Deputy Prosecutor Christine Keating claims that Marie Neumann pointed at several items in the store and her father put them in his bag. Both left the store with bags full of merchandise without paying for them.
The same situation allegedly occurred two days later, on Jan. 16: Marie Neumann tried to access the software room by using her hand in front of a motion sensor instead of the appropriate key card. The same security guard allowed Marie Neumann and her father inside. The two spent about 10 minutes in the store and allegedly left with bags of merchanise without paying.
After being confronted by their supervisors, Marie Neumann denied any wrongdoing, while Andrew Neumann confessed he was "guilty," court documents indicate.
The value of the items taken from the Microsoft Company Store was $6,946.50. The retail value was $41,023.
The security guard was not determined to be involved in the Neumanns' alleged scheme.
Microsoft reported that Marie Neumann posted a Facebook photo showing that she had doctored her key card to match the color of one a full-time employee would have used to gain access to the store.
Andrew Neumann has no criminal history. Marie Neumann has a criminal history, including a 2013 reckless endangerment conviction, as well as five criminal charges pending from incidents in 2012 and 2013.
