INDIANAPOLIS — Two killings early Friday have police investigating a staggering seven deaths in eight hours.

Two people were fatally shot just after 12:30 a.m. Friday. Those deaths came on the heels of a quadruple homicide on the city's Southeastside late Thursday.

Police found two men — ages 22 and 27 — inside a home on Stuart Street, said Lt. Chris Bailey of the Indianapolis Metropolitan Police Department.

One man was pronounced dead at the scene, Bailey said, and another died after being taken to Eskenazi Hospital in critical condition.

"Detectives have very little information about what led to this shooting," Bailey said in a release.

Sgt. Kendale Adams, a police spokesman, said the victims in Thursday's homicide are two men and two women.

Bailey said the motive and circumstances of the shootings in a home on South Parker Avenue, are unknown at this time.

Bailey said people who knew the victims saw their bodies and called 911 at about 8 p.m.

Detectives are still talking to neighbors and possible witnesses.

Animal control officers also were at the scene to deal with live animals found inside the house.

Josh Davis, 26, who lives a block from the shootings, said there is drug dealing in the neighborhood but little violence.

"You see the cars come through at all hours of the night, then leave, so it doesn't take a rocket scientist to figure out what's going on," Davis said. "But I've never seen a fight in the street or heard gunshots at night, anything like that."

Davis said many of the residents of the modest one-story ranch homes are elderly.

"That keeps it quiet around here," Davis said. "I know my immediate neighbors and everyone is friendly."

Another neighbor, Christina Wood, who lives three blocks away, said she was watching her and her friend's children in a house just a few doors down when the shootings occurred. She didn't hear gunshots, she said, but she heard the sirens.

"I'm a nervous wreck," Wood said as she lit a cigarette on the front porch of her friend's house on Parker Avenue.
