SAN FRANCISCO -- A man was shot and killed late Tuesday on the street where he lived in San Francisco's Mission District, in the neighborhood's second fatal shooting in less than 24 hours, authorities said Wednesday.

The latest victim, Edson Lacayo, 29, was shot several times on the 800 block of Hampshire Street at about 11:30 p.m. as he was walking his pit bull, Taz, his family said. He died at the scene.

Two men were seen fleeing the area. No arrests have been made.

Lacayo was shot just a few feet from his door, said a man who identified himself as Lacayo's cousin.

"He tried making it home," the cousin said as he stared at the ground.

A small shrine of candles, flowers and a stuffed-animal Taz, the Tasmanian devil character from the Looney Tunes cartoon, marked the spot where Lacayo died.

Beverly Chambers, who lives on Hampshire, said she and her husband had heard several gunshots and called 911. Paramedics arrived, but Lacayo "had passed away on the sidewalk in front of our small iron gate," Chambers said.

"There were many neighbors gathered outside and several people crying loudly," Chambers said. "Our block is usually quiet and pretty safe. I'm sure this has left everyone shaken."

Lacayo was slain about nine blocks east of the site of Tuesday's first shooting.

The victim in that incident, Gaspar Puch-tzek, was shot while taking a smoking break outside the Hog & Rocks restaurant at 3431 19th St., where he worked as a cook. The 22-year-old San Francisco resident was shot in the head at 12:30 a.m. and died at San Francisco General Hospital.

Co-workers said Puch-tzek had two children and worked two jobs to support his family. Investigators believe the gunman mistook him for a gang member.

Police described the killer and another man who was with him as being in their 20s and wearing dark clothing and hoodies.

The men ran west on 19th after the shooting, and no arrests have been made.
