A 17-year-old Sacramento boy was gunned down in the middle of a busy south Sacramento street Wednesday afternoon, the county's fifth homicide in less than 24 hours.
It was the second violent death within the city limits since 9 p.m. Tuesday, when a middle-aged woman was found stabbed in a downtown hotel, authorities said.
Also that night, a man was found shot to death in a Rancho Cordova parking lot.
And in Folsom, daybreak brought the discovery of a grisly double homicide and related suicide.
Wednesday's brazen shooting occurred on Florin Road about 2:30 p.m. Police believe the victim was on foot, walking along the road's north edge just east of Loma Verde Way, when he began fighting with at least two males in their late teens or early 20s, said spokesman Sgt. Matt Young.
The victim tried to run from his assailants, Young said, making it to the middle of the eastbound lanes before he fell, shot an unknown number of times.
His body remained there late Wednesday afternoon, covered with a tarp as police investigated.
A pickup truck and a sedan remained parked in the traffic lanes near the body. Their drivers were being questioned by police but did not appear to be involved, Young said.
The assailants were seen fleeing south on foot, Young said. As police saturated the area searching for them, at least two local schools -- Luther Burbank High School and Goethe Middle School -- were locked down.
About three blocks of Florin Road remained closed to traffic early Wednesday evening as police continued their investigation.
Officers moved from business to business along the busy thoroughfare looking for witnesses; a number were brought in for statements, authorities said.
No arrests had been made by Wednesday night.
Early Wednesday morning, though, an arrest was made in connection with the previous night's stabbing in the Sequoia Hotel, 913 K St.
Peter Brian Shearer and the victim -- identified by the Sacramento County Coroner's Office as 52-year-old Dawn Jean Brenda Trujillo -- got into an argument outside his fourth-floor apartment in the Sequoia, police said.
Trujillo was found in the hallway of the third floor with a stab wound to her right leg, authorities said. She died at UC Davis Medical Center.
A SWAT team went door to door looking for suspects, crime scene investigators examined bloody footprints left throughout the Sequoia's narrow hallways and detectives interviewed the hotel's manager.
By midnight, the investigation focused on Shearer. Patrol officers were given notice that he was wanted for questioning, and investigators scoured nearby bars and shelters looking for the man known as "Petey."
The suspect eventually returned to the Sequoia, where he was arrested on suspicion of voluntary manslaughter, police said.
What led to the death of a man in Rancho Cordova is less clear, authorities said.
Sacramento County sheriff's investigators are trying to identify the man found with a fatal head wound in a thrift shop parking lot in the 10000 block of Folsom Boulevard, according to department spokesman Sgt. Tim Curran.
Nearby residents told deputies they heard gunshots about a half-hour before the victim was found just before 11 p.m., but investigators do not know if the gunshots were related to the man's death, Curran said.
Anyone with information about any of the cases is asked to call Crime Alert at (916) 443-HELP.
The deaths brought to six the number of homicides within Sacramento city limits since the start of 2007. Five more have occurred within the Sheriff's Department's jurisdiction.
Phil Mendoza, a 33-year-old Elk Grove resident, lamented the latest violence as he stood outside crime scene tape on Florin Road.
As a groundskeeper at St. Mary's Catholic Cemetery & Mausoleum, he buried two victims of violence in the area last summer -- 17-year-old Robert Placencia, shot at the corner of Tamoshanter and Montecito ways, and 36-year-old Sylvia Guerrero, shot at a park on Loma Verde Way.
Mendoza described what he considers Sacramento's increasing violence as outrageous.
"It's terrible," he said.
"I moved from Los Angeles to get away from that."
