A Cobb County woman who was found dead in her residence and the man wanted in her death had a relationship at one point, police said.

Suspect Brian Marsh Semrinec, 24, and Shuyi Li, 28, also had a common employer, Cobb police Sgt. Dana Pierce told The Atlanta Journal-Constitution on Wednesday.

Pierce wouldn’t elaborate on the timing of their relationship, nor would he name the common employer, citing the nature of the search for Semrinec.

Semrinec, of Smyrna, is charged with felony murder and aggravated assault. Police are waiting for the Cobb County Medical Examiner to determine the official cause of death, according to Pierce.

Police found Li’s body Monday in her residence in the 2300 block of Willington Shoals Place in Smyrna, Pierce said earlier. Officers checked on her after she didn’t show up for work.

Police also have asked for help from the Cobb County Sheriff’s Office fugitive squad and the U.S. Marshals service in their search for Semrinec, Pierce said.

The suspect is believed to be driving Li’s white 2015 Honda CRV with Georgia tag CDD3152. Anyone with information about his whereabouts is asked to call police at 770-499-3945 or 911.
