A transient man has suffered life-threatening injuries in the vicinity of State Street and Broadway.

SAN DIEGO (CBS8/CNS) - San Diego Police on Thursday arrested 36-year-old Anthony Alexander Padgett of Chula Vista in connection with a four-day spree of violence that killed two homeless men and critically injured two others in various San Diego neighborhoods.

Padgett told CBS News 8 cameras, "That's not me in the pictures. I'm innocent."

Padgett will face two counts of murder and two counts of attempted murder.

According to police, after ten hours of questioning they believe he acted alone.

Padgett has denied the killings and attacks of homeless men.

According to San Diego Police, information given to them led to Padgett's arrest. Police did not discuss a possible motive for the attacks.

According to The Star News, Padgett was fined $414 in 2010 and served a four-year sentence after setting his friend on fire while he was asleep near a Chula Vista market.

Detectives did not say if Padgett is homeless, but searched camps and executed search warrants. Now that Padgett is in custody detectives are hoping scared witnesses will come forward with information to see if he is connected to other attacks leading up the series.

The search for Padget became a top priority for Mayor Kevin Faulconer and police Chief Shelley Zimmerman earlier this week.

During an update Thursday morning, SDPD Capt. David Nisleit said the "very violent person'' [Padgett] carrying out the brutal attacks may have been using public transportation and urged bus and trolley riders to be on the lookout for him.



Surveillance cameras at a convenience store near where the first victim was found captured images of a man believed to be the perpetrator. In the video footage, the dark-haired suspect, who appears to be in his 20s or 30s, is carrying a backpack and wearing dark gloves, light-colored pants, a brown long- sleeve shirt or jacket over a dark undershirt and a green short-billed Greek fisherman-style cap.



About 8 a.m. Sunday, the assailant killed 53-year-old Angelo De Nardo of San Diego and set his body on fire in an open area off the 2700 block of Morena Boulevard in Bay Park, according to police. An autopsy determined that De Nardo died prior to being set ablaze.



Shortly before 5 a.m. on Independence Day, transient Manuel Mason, 61,

was found bleeding from wounds to his upper body near Valley View Casino Center in the Midway district. He remains hospitalized in critical condition.



Less than 90 minutes after the assault on Mason was reported, 41-year-old drifter Shawn Longley was discovered dead at a park on Bacon Street in Ocean Beach.

About 5 a.m. Wednesday, a 23-year-old homeless man was gravely injured in the area of Broadway and State Street, and a towel he was sleeping under was doused with a flammable liquid and set ablaze, according to police. The victim, whose name has not been released, was hospitalized in extremely critical condition and had a poor prognosis for survival, officials said.



Authorities have declined to disclose the cause or causes of the targeted men's non-fire-related injuries, though Nisleit said all four victims had suffered significant trauma to their upper bodies.



Over the last five days, police have been warning the homeless to protect themselves by remaining vigilant and aware of their surroundings at all times, avoiding sleeping alone on the streets and staying in open, well-lit areas.

Late this morning, Father Joe's Villages, a major local homeless- services provider, announced that it was seeking funding to provide additional beds at its downtown St. Vincent de Paul Village shelter as a means of helping protect those who have nowhere else to stay.

On Wednesday, the police chief told reporters that she had made bringing in the perpetrator of the attacks her officers' primary objective as they go about the rest of their daily duties.



"These evil acts of violence are some of the worst that I have seen in my 34 years in law enforcement,'' Zimmerman said. "This killer has targeted some of our city's most vulnerable citizens while they are asleep.''



The mayor said police officers were fanning out to make those in the transient community aware of the attacks and to keep them safe.



"These crimes against some of our city's most vulnerable people are absolutely reprehensible,'' Faulconer said.
