A Kalihi man accused of gunning down his ex-girlfriend in broad daylight on an Ewa Beach street is facing life in prison without the possibility of parole if convicted of first-degree murder.

Prosecutors charged Toi Nofoa, 31, at about 8:45 last night with first-degree murder, second-degree murder, use of a firearm in commission of a felony and a firearm violation. His bail was set at $4 million.

His alleged victim, Royal Kaukani, 25, was going to testify against him in a kidnapping case, which prompted the first-degree murder charge. Nofoa allegedly forced Kaukani into a car at gunpoint on Sept. 11 and threatened to kill her.

Kaukani's death is believed to be the third domestic violence-related homicide in Hawaii this year.

Domestic violence experts said homicides related to domestic violence have increased recently, although there is no clear reason why.

“;Last year was a gruesome year for domestic violence homicide,”; said Carol Lee, executive director of Hawaii State Coalition Against Domestic Violence. “;This is proving to be another bad year.”;

There were 12 domestic violence-related homicides last year, including four murder-suicides and a good Samaritan who intervened and was stabbed at a bar. In 2007, there were seven.

“;We have received a lot of calls from concerned individuals,”; Lee said. “;The information is starting to penetrate the community, and people are coming to realize what a serious problem this is in Hawaii.”;

At Kaukani's house last night, her family, including six sisters and extended family, gathered to thank the community for their support and to celebrate her life. A memorial fund has also been set up in her name.

Kaukani, a 2001 honors graduate of Waianae High School, was a concierge at Ko Olina Activities.

Family spokesman Raymond Donato said he remembers her beautiful smile, loving spirit and positive attitude.

“;You just got to smile and be happy, and that's the memory I have of her that helps me move on,”; he said. “;She always carried herself as a caring, loving person.”;

Donato said people have been placing flowers at a memorial where she was killed and calling the family to offer help.

“;There's been overwhelming support from the community,”; said Donato. “;The family is doing well.”;

He declined to speak about Nofoa.
