HONOLULU (AP) — A Hawaii man wanted in the killings of three men within two days in a rural area on the Big Island, where tropical landscapes mix with barren lava fields, had been accused of threatening and harassing behavior earlier this month by two women, according to court records.

Jacob Baker, 36, of Pahoa, Hawaii, was described by police as “armed and extremely dangerous,” and Hawaii Police Chief Reed Mahuna said authorities were deploying “significant resources and personnel” in trying to find him.

Authorities said they believe he is involved in the deaths of three men: a 69-year-old man found partially submerged in a cement pond, a 79-year-old man who was found just 400-500 feetaway, and a third man, also 69, whose body was found about 19 miles away. The causes of death were not immediately disclosed.

“These are a tragic series of events and our thoughts are with those who are grieving at this time,” Mahuna said at a news conference Wednesday. “The Hawaii Police Department understands the fear and concerns incidents like this bring to our community.”

Authorities said they had not identified a motive but were confident Baker was involved in all three homicides. Mahuna did not release information on how police identified Baker as a suspect or what evidence may connect him to the killings. He said investigators had not identified any connections among the victims, other than two of them lived near each other.

The slayings happened just days after two women had requested temporary restraining orders against Baker, saying he had threatened and harassed them at a farm; one woman was staying there and the other co-owned it. A judge denied both applications, saying there was not enough proof of harassment provided.

One of the women claimed in her petition that Baker had threatened to kill several women who were staying on the property, and had caused a number of them to move or end their stays. She included a link to a video that allegedly captured at least one threat, but the link had either been removed or was incorrect as of Thursday.

The other woman alleged in her petition that Baker had threatened women and a disabled man, and said he would trespass on the property, take things that didn’t belong to him and say his intention was to squat on the property.

No attorney was listed for Baker, who had 20 other cases in the court record in the past two decades, many of them traffic infractions. There were also a handful of criminal or administrative citations including letting a dog wander, failure to appear in court and simple trespassing.

In most of those cases, Baker represented himself.
