Lafayette police investigating the killing of a woman whose body was found in a tool box Tuesday say they have located a vehicle that detectives had believed played role in the case.

The Lafayette Police Department now says the vehicle - a 2002 green two-door Honda Accord - is being examined but probably is not central to the case.

The body of Alannah L. Montalvo, 23, was found Tuesday on South Wilderness Trail in north Lafayette.

Police believe her killer was Barrette B. Farabee II, 36. The two are believed to have been in a relationship, police said.

In a bizarre twist, Farabee was killed Friday morning by a Fanny Street homeowner when he trespassed, naked and armed, on to the homeowner's property.

The investigation continues.

Original story

A naked trespasser who was shot and killed by a homeowner last week is a suspect in the death of the woman whose body was found Tuesday in the Wilderness Trail area, Lafayette police said.

Police on Wednesday identified the victim as Alannah L. Montalvo, 23, of Lafayette.

Investigators responding to a tip discovered her body around 4 p.m. Tuesday stuffed in a large toolbox in the 300 block of South Wilderness Trail.

Police said the man suspected in her death is Barrett B. Farabee II, 36, who was shot and killed around 8 a.m. Friday by a homeowner on Fanny Street who encountered Farabee naked and wielding a gun in his backyard.

Police said in a news release that Farabee and Montalvo were in a relationship and that forensic evidence and statements connect him to her death, but they declined to give details on the nature of the evidence.

Lafayette Police spokeswoman Cpl. Bridgette Dugas said investigators are now focused on finding a green, two-door 2002 Honda Accord with Tennessee license plate "505JGQ."

She said both Montalvo and Farabee are believed to have used the vehicle.

Montalvo has no known connection to the homeowner who shot Farabee, and police still don't know why Farabee was in the man's yard, Dugas said.

"They are complete strangers," she said.
