A 33-year-old woman and her older boyfriend were sleeping in their Vero Beach bedroom about 2:30 a.m. when the boyfriend's wife stormed in with a rifle.The wife, identified as Brenda Schumann, 51, pointed the weapon at her 42-year-old husband and his younger girlfriend, threatening to kill them both, according to accounts given by Schumann's husband and his girlfriend.The husband got the gun away, but that didn't stop Schumann's apparent rampage.She urinated on the carpet outside the master bedroom, defecated on the kitchen floor, grabbed a second rifle and started destroying Christmas decorations and other things."I found him in bed with a naked chick what was I suppose to do," Schumann is quoted as telling an Indian River County Sheriff's deputy following the December 21 events, according to a recently released sheriff's report.Schumann and her husband are divorcing and have been separated for months, her husband and his girlfriend told investigators.They said they didn't know what prompted Schumann to show up at the home in the 5500 block of 12th Street at such an hour and start an armed confrontation.Schumann eventually left the second rifle in the dining room and vacated the premises. Investigators found her at an apartment in the area.Without being asked any questions, Schumann said, "I found him in bed with a naked chick what was I suppose to do."It could be argued that better options exist than having an armed encounter, urinating and pooping in non-standard places and destroying seasonal decorations and other items.Schumann, of the 5500 block of 12th Street in Vero Beach, was arrested on charges including aggravated assault/domestic violence, aggravated assault, battery and resist arrest without violence.
