Two people were killed and three others wounded in three separate shootings in Seattle late Tuesday and early yesterday.

The first incident was in the Lake City neighborhood, in the 3000 block of Northeast 140th Street. Around 10:45 p.m. Tuesday, a man in his late 20s was found dead behind the wheel of his car parked in front of a house.

Seattle police spokesman Duane Fish said the man had been shot through the neck.

Police do not believe it was a random shooting, citing "a number of leads to go on," though no arrests have been made, said Deanna Nolette, a spokeswoman for Seattle police.

The second fatal shooting occurred around 2:40 a.m. yesterday at North 92nd Street and Woodlawn Avenue North, just north of the Green Lake neighborhood. According to Fish, two brothers, ages 23 and 26, were standing on the street corner as a car with two men inside pulled alongside. The two men in the car accused the two brothers of stealing a car stereo the night before.

"An argument ensued over whether or not the suspects had been involved," Fish said. "It was an apparent mistaken identity. ... "

At one point during the argument, the driver stepped out of the vehicle, retrieved a gun from the trunk, and shot the 26-year-old brother in the neck, killing him, Fish said.

The 23-year-old brother, who was not injured, took down a detailed description of the suspects and the vehicle, including the license-plate number. University of Washington police saw the vehicle pulling into an apartment complex in the University District.

The driver was arrested on suspicion of homicide, while the passenger was booked on a warrant on unrelated charges.

The third incident, a drive-by shooting in South Seattle at 2:30 a.m. yesterday, injured three people.

A 19-year-old woman and her two passengers were traveling on Martin Luther King Jr. Way South when the driver thought she recognized the vehicle behind her, police said.

As the woman's car slowed down, the two to three people in the car behind her opened fire.

The driver was wounded in the shoulder. One passenger, 19, was struck in the hand, and a second passenger, also 19, was shot once in the abdomen. Nolette said none of their injuries appeared to be life-threatening.

Seattle police say they have few leads in the incident.
