Police investigations continue into the worst shooting incident in Lake Havasu City’s history that left five Havasu residents dead and one injured, but police say the sequence of shooting events may never come to light.

“We may never know or be able to establish the exact sequence of events inside the home,” said Lake Havasu City Police Department spokesman Sgt. Joe Harrold. An interview with Debbi Nyland could provide some insight into the event, however, a person’s memory retention during a tragedy such as this may be limited, Harrold explained.

Harrold was able to provide a few more details of the homicide scene during an interview Wednesday.

“The door (of the residence) was locked when officers arrived. Possibly the door was locked by Debbi Nyland after (Diez) left the residence, but we don’t know that for sure. Our officers kicked the door in when they arrived,” Harrold said.

Sunrise Hospital & Medical Center spokeswoman Ashlee Seymour said Wednesday Debbi Nyland remains in good condition. Nyland was airlifted to the Las Vegas-based hospital in critical but stable condition Sunday, following the incident.

The recordings of Debbi Nyland’s eight-minute 911 emergency call just before midnight Aug. 28, included information about the incident in a rather calm tone considering the circumstance.

“There are like at least four or five people shot … I am shot. I think in the neck … there are so many people shot,” Nyland told the emergency dispatcher. Nyland also told the dispatcher the three people nearest her, including her husband, were “all on the floor” and that “it was one person” who entered the residence and started shooting with a handgun.

“I think my husband is dead,” Nyland said at one point, but she was unable to get over to him to see if he and Broc Kelson, both located in the kitchen and dining room area, were breathing. “My daughter is also in the house, please hurry,” Nyland said. Nyland also told the dispatcher “you’ll need more than one ambulance.”

The recordings continued as dispatchers learned the involvement of Langstaff’s young children who Diez fled the scene with.

“There was a 4-year-old and a 1-year-old, and the person who shot everybody was in a blue T-shirt with brown hair and he took the 4-year-old,” Nyland continued to tell the dispatcher during the recording.

“OK Debbi, my fire department is on the way they should be getting there any minute and I have got some officers who should be coming into the house, OK? Is your door open? Are they able to get in?” the dispatcher asked.

“I have no idea,” Nyland answered.

“So just to make sure, there is four people that are injured and there was only one person with the gun … you don’t know where your daughter is and they left with the child?” the dispatcher asked.

“Uh huh, and somebody else,” Nyland said.

“What do you mean somebody else?” the dispatcher asked

“I don’t know who else, whoever the girlfriend was, I have no idea … please hurry … it hurts bad,” Nyland said just before the telephone connection was lost.

Afterward at the scene, Sgt. Harrold said it appeared as though the occupants of the residence in the 300 block of Opossum Drive that night were engaged in normal leisurely activities before 26-year-old Brian Diez entered the residence and began his shooting spree.

During initial investigations, police located deceased homicide victim 24-year-old Primo Verdone in the front room of the residence. Injured gunshot wound victim and sole survivor Debbi Nyland, 44, and decedents 42-year-old Russ Nyland and 20-year-old Broc Kelson were in the kitchen area. Decedents Ashleigh Nyland, 20, and Deborah Langstaff, 23, were together in a bedroom.

“There are not a lot of answers because everybody is deceased, and we have not interviewed the survivor (Debbi Nyland) yet,” Harrold said.

The alleged murder weapon, a .40 caliber semi-automatic handgun was retrieved from San Bernardino County Sheriff’s Department Tuesday and is currently in the possession of Lake Havasu City Police Department.

The next step in the Havasu detectives’ investigation includes sending the weapon to the firearms examiner at the state’s firearms/forensics lab in Flagstaff. The weapon will be examined and undergo ballistics testing to ensure it was the weapon used in the murders.

“Detectives are still in daily contact with the family members for questions,” Harrold said.

Gabriel Morales, supervising deputy coroner of San Bernardino County Sheriff’s Department/Coroner’s Division said Wednesday that Diez’ autopsy examination was completed Aug. 30. The examination determined the “cause of death was a gunshot wound to the head,” Morales said.

Morales would not comment on the type of weapon Diez used during his suicide at a residence in Rancho Cucamonga, Calif., because of the pending homicide investigations surrounding Diez. Morales also declined to comment on health condition findings the examination would have discovered. Morales did say Diez’ toxicology report would be ready in 8 to12 more weeks.

Services for Broc Kelson will be at 11 a.m. Friday at the LDS chapel, located at 510 North Acoma Blvd., in Havasu. Graveside services will follow at Lake Havasu Memorial Gardens. An open house celebration for Broc will be in Salt Lake City, Utah. A memorial fund has been set up in Broc Kelson’s name at any Wells Fargo Bank.

A letter to the editor e-mailed to Today’s News-Herald has suggested the community honor the victims, their family and their friends by wearing black armbands or ribbons Saturday in the wake of the tragedy.
