Victim's mother-in-law interviewed in shooting

SNELLVILLE - Police aren't calling the mother-in-law of the young mother from Conyers shot to death in front of her infant son a suspect, but said they have interviewed her twice.

Heather Strube, 25, was gunned down in a Target parking lot in broad daylight on April 26 after witnesses said she argued with the suspect, who appeared to have bushy hair and a moustache.

After viewing video surveillance, investigators released a sketch and said they believed the shooter could be a woman.

The white pickup truck authorities said was seen behind the shopping center belongs to Strube's mother-in-law, investigators said. They have not identified the mother-in-law. A phone call to Snellville police Chief Roy Whitehead was not immediately returned Friday.

The truck has been sent to a Georgia Bureau of Investigations lab to be combed for trace evidence, authorities said, and results could take weeks.

Strube's estranged husband, Steven Strube, 25, of Lilburn, had just driven off when his wife was attacked. The couple often used the parking lot as a point to swap custody of their 18-month-old son, reports said. Police said Steven Strube is not a suspect in the slaying, but Whitehead said last week that his department is considering every other angle.

"Nothing else is ruled out," Whitehead said.
