Ten hours would pass, during which time Grogan cut a hole into a neighboring apartment, burrowing through the walls in a desperate attempt to outfox the phalanx of officers who had surrounded the complex.
He eventually freed the male hostage but kept the female prisoner, sexually assaulting her at gunpoint. She fled the apartment after the defendant fell asleep.
He was awakened by police, who stormed the apartment once both hostages were accounted for.
Grogan was convicted Wednesday of rape, aggravated sodomy, kidnapping, false imprisonment, armed robbery, aggravated assault, criminal damage to property and weapons violations.
His attorney, Kenneth Schatten, said Grogan had been haunted by demons ever since the 2009 murder of his mother.
Minka Grogan was killed by ex-boyfriend Calvin Myers in April 2009 after he crashed his car through the front wall of her Roswell apartment, where he proceeded to stab her 16 times and beat her with a landscaping rock. Myers later pleaded guilty to murder and other charges and was sentenced to life in prison.
Tyler Grogan’s aunt, Anita Grogan, told the AJC in 2011 that her nephew grew “angry, confused (and) mad at the world” since his mother’s death.
