BRENTWOOD – As Sheila LaBarre's defense team began to wind down its case yesterday, jurors heard from several witnesses, including former tenants, who described bizarre interactions with the admitted killer.

Clarence Beaudette testified that LaBarre once tried to force him to do plumbing work for free after he was called to her remote Epping farm to fix a leaky faucet. LaBarre has admitted to killing two men, Kenneth Countie and Michael Deloge, on the farm, but is now pleading insanity.

Beaudette said the plumbing company he worked for dispatched him to the farm after LaBarre reported a leaky faucet. He described seeing a man, possibly Deloge, who did not speak but waved him into the house, where LaBarre was waiting, surrounded by rabbits. Beaudette said there were so many rabbits he couldn't pick up his feet and had to shuffle through to avoid stepping on them.

Beaudette said once he was in her kitchen and looked under the counter, he immediately could see that LaBarre's sink was not connected to any piping. But as he crouched down to look underneath, LaBarre insisted that wasn't the problem and kept urging him to lean in.

"'It's underneath, you have to look way underneath,'" Beaudette said, repeating what LaBarre told him as she stood behind him and urged him to lean further under the sink.

Beaudette testified that he became suspicious, and gave LaBarre a false quote for the cost of fixing the sink -- $1,200 -- which he assumed she would decline to pay. Beaudette said LaBarre became angry and started shouting that he would have to fix the sink for free. Beaudette said he tried to leave, but LaBarre grabbed his arm, and shouted that he should stay.

"I asked her to please not touch me, and she grabbed me again and said, 'You're not going anywhere, you will not go,'" Beaudette recalled. "And I said, 'I will go, and if you touch me again, I will kill you.'"

Beaudette said he left the house, shuffled through the rabbits blocking his way and went to climb in his truck, but LaBarre grabbed him again. He said she also ordered Deloge to shut the gate, and stand in front of it. Only when he actually got into his truck and began driving toward the gate did LaBarre order the gate be opened.

Beaudette said he called the Epping Police and spoke with Sgt. Sean Gallagher. Gallagher was one of two Epping Police officers who saw LaBarre with a battered and ill-looking Countie in the Epping Wal-Mart, just days before he disappeared. The two officers did not intervene. Yesterday, Beaudette testified that Gallagher laughed when he began describing the situation and said that most delivery services refused to go to her house anymore.

Several former tenants of LaBarre also testified about bizarre interactions they had with her when they lived in apartments she owned in Somersworth. Amy Marshall testified that she and her family lived in an apartment owned by LaBarre for about six months. She said things went well until their furnace broke in November 2005 -- around the time investigators believe Deloge was murdered. LaBarre initially told them she had no money to fix it, and they would have to deal with it. Marshall said they refused to pay their next month's rent, unless LaBarre deducted the cost of heating the home with space heaters, which enraged her. Marshall said they began getting harassing phone calls almost every day from LaBarre, who would scream obscenities.

The only respite was on Christmas Eve, when LaBarre left them flowers on their back doorstep, and Christmas Day. LaBarre explained that she cared about Marshall's children and that's why she didn't call those two days.

As the family was moving out in January of 2006, Marshall said she believes LaBarre poured bleach into several fish tanks that were left in the house overnight, killing all of the fish. Marshall also described discovering a nearly new mattress that had been briefly left in an upstairs bedroom, that someone seemed to have smeared blood on.

In ordinary criminal cases, the defendant is presumed innocent and it is up to prosecutors to prove their guilt, but in this case, LaBarre is presumed to be sane, and the burden is on the defense to prove their claim. A final expert witness is expected to testify on Tuesday, and prosecutors anticipate starting their rebuttal shortly after.

Defense attorneys are arguing that LaBarre suffers from psychotic delusions that lead her to believe that all men are pedophiles and that she is an avenging angel sent by God to protect children and animals. LaBarre killed Countie and Deloge based on those delusions, they have argued.

Prosecutors have worked to undermine these claims, pointing to LaBarre's apparent attempts to hide her crimes by destroying both men's bodies and then attempting to flee the area. Prosecutors say LaBarre may be mentally ill, but it falls short of legal insanity and she is simply mean and controlling.
