The day after Mike Yuchnitz, 59, was arrested on charges that he attempted to hire a hitman to kill his wife, Tina, she filed for divorce.

On Wednesday, the couple’s divorce trial got underway before 408^th District Judge Larry Noll. 

Yuchnitz testified that the couple worked together as he started his eyewear business in the ‘70s. 

It grew to a chain of 19 stores in San Antonio, Laredo and Kerrville called "My Econo 39.95" 

She is seeking his estate which his lawyers say is valued at nearly $7 million -- including a $1.2 million tattoo business the couple’s son owns.

In October 2010, Yuchnitz was arrested and charged with murder-for- hire. 

Investigators said he tried to hire a hit man to kill his wife.

The divorce trial reportedly could take up to two weeks. 

Yuchnitz’s trial in the murder-for-hire case is scheduled to begin on March 16.
