A missing Sonoma State University freshman was found dead in Annadel State Park in Santa Rosa on Saturday, his body located in brush off a trail near Lake Ilsanjo, authorities said.

James Abriel, 19, appeared to have died of a self-inflicted gunshot wound, Santa Rosa Police said.

A 40-caliber Sig Sauer handgun taken from his parents' home in Walnut Creek was found with his body, police Sgt. Steve Fraga said.

Authorities also found two suicide notes in his backpack, Fraga said.

A total of five notes have now been recovered - one from the Walnut Creek house, two others from Abriel's student residence at SSU and the two found Saturday, he said.

A cadaver dog and its handler, who were among an army of 110 search and rescue personnel scouring the park Saturday for a second day, located Abriel's remains about mid-morning Saturday, authorities said.

It was another hour or so before a Sonoma County coroner's detective and a police evidence technician could be dropped at the site by helicopter to confirm that it was Abriel.

Abriel's parents and several other relatives had kept a private vigil all day Friday and Saturday morning at a picnic site near the south end of Spring Lake.

After being informed that her son's body had been found, Evangeline Abriel said that she and her family "are really just overwhelmed by the outpouring of help and the resources here."

The family was accompanied by two members of the Sonoma County Law Enforcement Chaplaincy and, for a second day, an assistance dog aimed at providing comfort and diversion, handler Nancy Pierson said.

Abriel said the family also appreciated news coverage of the search for her son, which included a description of his car and its license plate number, which ultimately led authorities to search Annadel.

An A student and accomplished musician, Abriel was reportedly despondent about a recent break-up when he was last seen by a friend in Walnut Creek on April 21.

The first notes were found four days later, indicating what he had planned. Abriel was reported missing April 28.

The use of his debit card at a Rohnert Park 7-Eleven on April 22 and a signal transmission from his cell phone when he apparently accessed voicemail from Santa Rosa on April 25 put him back in Sonoma County, focusing the search there.

On Thursday afternoon, a resident of Parktrail Drive at the edge of Annadel, realized that a white Toyota Camry parked there for more than a week matched descriptions of Abriel's car.

Authorities searched the area Thursday night and early Friday set up a command post and large-scale operation that lasted 12 hours Friday. They resumed early Saturday for about four hours before discovering Abriel's body.
