RESERVE — Physical evidence is being processed and community members are cooperating with detectives as the St. John the Baptist Parish Sheriff’s Office works to solve a violent rape that shocked Reserve residents last week.

Police said a woman arrived home on Northwest Third Street in the early morning hours of Thursday when an armed black male dressed in black clothing and a ski mask approached.

According to authorities, the female ran into her home and tried to lock the door but was attacked by a second black male armed with a gun.

The two armed men forced their way into the female’s home, police said, where they robbed her. Sheriff Mike Tregre said one of the assailants sexually assaulted the victim before they both fled on foot.

Anyone with information about the rape and robbery is encouraged to call the Sheriff’s Office TIPS line at 985-359-TIPS, dispatch at 985-652-6338 or the Criminal Investigations Division at 985-652-2773.

Tregre said the assault appears random, as evidence collected does not suggest the victim was specifically targeted.

Detectives do not necessarily believe this was the assailants’ first such crimes.

“They could have done this before, but we haven’t had this,” Tregre said Monday afternoon. “We’re checking with multiple agencies to see if this happened anywhere else. For two guys to wear ski masks and be armed in a rape case, that is kind of unusual. We’re looking at previous arrests because it’s hard to believe somebody just decided put a ski mask on, arm themselves and commit this kind of crime for the first time ever.”

In the aftermath of the vicious attack, Tregre said it is imperative for residents to be aware of their surroundings and use 911 whenever suspicious.

“The first thing we want to do is alert the public to be on guard, protect themselves, lock your doors, set your alarms and call 911 anytime you feel threatened,” Tregre said. “If you drive up to your home and see a guy outside your door or home, you can call us, especially if you don’t know who he is. Don’t hesitate to give us a call.”

According to authorities, physical evidence collected at the scene has been sent to the crime lab for processing and local residents are helping provide details.

“(The neighbors) couldn’t believe when they saw us back there (investigating),” Tregre said. “We’re working it and will take any tips at all. The biggest thing we have right now is physical evidence going to the lab.”
