Denver Officers Continue Work Of Slain Colleague

Celena Hollis Was Planning Bone Marrow Drive

Colleagues of a Denver police officer shot while trying to break up a fight are continuing some unfinished work for her.

Officer Celena Hollis planned to have Denver's Black Police Officers Organization host a bone marrow drive to increase the number of African-American donors. The organization will hold the drive in her honor on Friday.

She wanted to find more donors after hearing about a Colorado Army National Guard member in need of a live-saving marrow or stem cell transplant.

Staff Sgt. Mark Jenkins being diagnosed with myelofibrosis, a chronic leukemia that ultimately effects the bone marrow. The disease has a prognosis of five to 10 years -- unless he can get a life-saving bone marrow or stem cell transplant.

The bone marrow drive is 11 a.m. to 2 p.m. at the Denver Police District 2 station located at 3921 Holly Street.

The sign up procedure takes 15-20 minutes and a cheek swab.

Remembering Celena

Hollis was killed on June 24 while trying to break up a fight following a jazz concert at Denver's City Park.

Twenty-one-year-old Rollin Olliver is accused of firing multiple rounds during the altercation, and police say one of his shots allegedly hit Hollis, a former Detroit police officer, in the head.

Hollis was a single mother raising a 12-year-old daughter, and was well-known in the department and in Denver, said Hancock.

"She was a very pleasant, extremely pleasant, polite officer. She had a phenomenal reputation," said Denver Police Chief Robert White.

Hollis had spent seven years in the Denver Police Department and was an officer on the police force in Detroit before she transferred in October 2005.

"She served as a patrol officer in District Two and was a member of the Street Crime Attack Team (SCAT)," according to an online bio on the Denver Police Department's website. Officer Hollis has been recognized numerous times for her outstanding performance and service to the community.

Donations for Officer Hollis’ daughter and family can be made to the Celena Hollis Memorial Fund, Rocky Mountain Law Enforcement FCU, 700 W. 39th Avenue, Denver, CO 80216.

Hollis is the first Denver police officer killed in the line of duty since 2005.
