A 64-year-old man is accused of killing another man, wounding a woman and shooting and killing the woman’s dog after a long-standing dispute with the two who were camping on his property in Northeast Portland, according to Portland police and court records.

Reza Chehrazi Mardani was booked into the Multnomah County Detention Center at 4:14 a.m. Friday, accused of murder, attempted aggravated murder and unlawful use of a weapon.

Portland police Sgt. Pete Simpson said the killing was not a domestic violence-related homicide, yet investigators believe that all involved were associated with the residence and property where the shooting occurred.

Portland police were called to the home at 5287 N.E. 74th Avenue Thursday afternoon about 4:30 p.m. on a report of gunfire.

A neighbor, Juliana Mejia, told The Oregonian/OregonLive that she heard gunshots and a woman screaming.

Another neighbor, Petru Rachi, said he was working in his backyard on Northeast 73rd Avenue. "I hear ‘pop,pop,’ and then I heard someone yelling ‘help, help!’ '' Rachi recalled. "Then I hear another two ‘pop, pop,’ and then quiet.''

Officers found George Michael Atkeson, 62, dead and Darlene Marie Kelley, 63, wounded on the property. Kelley was reported to be in serious condition in a local hospital on Friday.

Kelley’s dog also was shot and killed, police said.

Mardani had obtained a temporary stalking protective order against Atkeson in September 2018, saying Atkeson was living in a camper on his property and wouldn’t leave, court records show. Portland police had been called to the property several times before the homicide occurred.

Mardani wrote in his Sept. 12, 2018 petition for the stalking order that every time he asked Atkeson to go, Atkeson would confront him.

Atkeson had punched Mardani and knocked him to the ground on Sept. 7, and Mardani called police and sought the stalking protective order, records show.

Mardani wrote in his petition that Atkeson’s camper was parked on his property, filled with garbage and attracting several women and other transients. When confronted in September, Atkeson told Mardani that he’s not moving, has no other place to go and that Mardani couldn’t force him to leave, Mardani wrote. Atkeson had promised he "will make my life as hell from now on,'' Mardani wrote in the stalking order petition.

Mardani also was perturbed that Atkeson had moved the belongings of a female friend into a shed on his property.

"He has physically assaulted me, damaged property,'' Mardani wrote in the petition. " I believe he may kill me.''

Mardani had been working as the full-time caretaker for his brother, Mohammad Mardani, 66, but his brother passed away two weeks before Christmas 2017, according to court documents.

In June 2017, Reza Chehrazi Mardani was arrested, accused of violating a court stalking order obtained by another woman living on his property, Amber Cherie Barnett, 40. Mardani’s brother Mohammad Mardani, according to court records, had allowed Barnett to live on their property because she had a heart problem. Reza Mardani , though, believed she was trespassing. The charge ultimately was dismissed, and the stalking order Barnett had obtained against Reza Mardani in June 2017 was dismissed two months later.

Mardani, a native of Iran who had served as a corporal in the Iranian army, has lived in the Portland area for more than 20 years, according to court records. He has one prior misdemeanor conviction in 2010 for tampering with government records.

Mardani is not scheduled to be arraigned on the allegations in Multnomah County Circuit Court until Tuesday afternoon because he was booked into jail after 2 a.m. Friday.
