HAYWARD -- After more than four years, three men have been arrested and charged with murder in connection with the slaying of an 80-year-old Hayward woman.

Donnie Tony Howard, 24; Lionel J. Harris, 22; and Ayodele Patterson, 21, appeared Tuesday in Alameda County Superior Court to be arraigned on murder, burglary and robbery charges in the March 26, 2010, fatal shooting of June Carolyn Pavon.

The senior, who lived at 25352 Spring Drive, was found shot to death the next day in her house on a quiet cul-de-sac in the Hayward hills.

Pavon, a grandmother who lived in the home with her small dog, was last in contact with relatives two days before she was found dead, police said. Relatives visited her home and found her body after she did not answer their phone calls.

New information released in court documents Tuesday revealed the men entered Pavon's home by forcing open a garage door so they could burglarize the residence.

While inside, court papers show, the men confronted the senior; Patterson, who was age 17 at the time, shot her with a .22-caliber rifle as she sat on her couch and read a book.

Court documents reveal she was shot twice in the chest and twice in the head.

After she was shot, the trio ransacked the bedrooms in the home along with Pavon's purse, which was found on the floor near her body. They then fled the home with cash and jewels, Sgt. Mark Ormsby said.

A probable cause affidavit revealed that Howard was arrested in 2011 for an unrelated burglary. During an interrogation for that crime, he told detectives that Patterson and Harris were responsible for Pavon's death. Howard remains in custody, awaiting sentencing on a burglary conviction; he was placed under arrest in the homicide on Friday.

Patterson was arrested Friday in Oakland, and Harris was taken into custody Friday in San Francisco, Ormsby said. At the time of his arrest, police say, Patterson admitted being in Pavon's residence at the time of the killing with Harris.

In an interview with detectives, Harris said that on the day of the killing, the trio walked from Howard's apartment -- just two blocks from Pavon's home -- to her residence to burglarize it. He said Howard kicked in the garage door, and Harris said he planned to go inside and "lay the victim down," the affidavit reads. Patterson, he said, confronted the senior and said, "Give it up, old lady."

Pavon's home was burglarized twice in 2010, police said, most recently one month before her death.

At the time of her death, neighbors said they would wave hello to Pavon but did not know her well. They said she was a widow whose husband died around 2002.

The suspects were being held without bail Tuesday at the Santa Rita Jail.
