Police investigating double-fatal shooting inside Hempstead home

Family members returned to the scene of a double-fatal shooting a day after Wednesday's shooting in Hempstead.

Officials said the gun violence happened just before 10:30 a.m. Wednesday inside a home at 16 Angevine Ave. 

The sister of the victims, who she identified as 52-year-old Dave Adamson and 49-year-old Gary Adamson, told CBS News New York her mother called her in the morning and told her she couldn't get into her office.

When the sister arrived at the house, she says she found her brothers dead inside on the first floor.

The block was cordoned off with police tape, and the Nassau County Police Department's Homicide Unit launched an investigation.

Police and other local authorities spent hours scouring the home and the surrounding area, trying to reconstruct the moments leading up to the deaths of the two men.

The victims' sister, who did not want to share her name, says one brother cared for their parents while the other worked at a church. Both brothers lived with their parents, she said.

"They were good people, very loving people," she said.

"That was my heartbeat. That was my whole world," said a childhood friend of Dave Adamson's. "He was like a brother to me. He was everything."

People living in a nearby senior housing complex watched the police response unfold.

"I was on my way somewhere else. I seen a bunch of police coming over here and when I came back, I seen everyone out there and I seen the tape and I knew something had happened," one person said.

For people who live just steps from the home where the gun violence erupted, the incident was both disturbing and unsettling.

"They didn't have time to defend themselves, and it's very devastating," one neighbor said. "They were very young, good gentlemen, good people."

"I feel for them. My heart goes out," another said.

"I am shocked," another person added. "It's scary, right in front of where I live."

The Hempstead police chief says both victims died of gunshot wounds, but the sister says they are waiting for an autopsy to make the final determination.

Police have not announced any arrests or identified a suspect. Officers said they don't believe there's any additional threat to the public. 

Anyone with information is asked to contact Nassau County Crime Stoppers at 1-800-244-TIPS or call 911. All callers will remain anonymous.
