(SNELLVILLE, Ga.) -- Heather Strube was in a bitter custody dispute with her husband Steven in April 2009 when she was confronted by a "man" in a Georgia parking lot who put a gun to her head and shot her.
That man, prosecutors allege, was Heather Strube's mother-in-law, Joanna Hayes, disguised in a wig and moustache. And on Monday, Steven Strube was scheduled to testify in his mother's murder trial.
Heather and Steven Strube were battling in court over custody of their 18-month-old son, Carson, at the time of the murder. The couple agreed to meet in the parking lot of a Target store in Snellville, Ga., on April 26, 2009 so Steven could hand over Carson to Heather. After the handover, Steven drove away and Heather strapped the boy into a car seat when the gunman arrived at Heather Strube's car, put a gun to her head and shot her. The boy was unharmed.
Prosecutors allege Hayes donned a disguise and shot Strube because she didn't want her daughter-in-law to have custody of her grandson. Hayes' defense team denies her involvement in the murder.
Testimony and evidence has thus far implicated Hayes. Former co-worker Paul Pinzino told the court that Hayes had spoken of plotting the perfect murder. To hide evidence of the crime, Hayes allegedly told Pinzino she would melt the gun. Police have never found the murder weapon used to gun down Heather Strube.
Nearly eight months after the crime, Hayes was arrested and charged with murder in December of 2009.
Snellville police said that surveillance video revealed that the killer wore a wig and fake mustache, ABC News affiliate WSB-TV reported. Surveillance video shows what looks like a man wearing khaki pants with a shirt tucked into the pants.
