COMPUTERS STOLEN FROM SAN BRUNO SCHOOL: SAN BRUNO  (AP) — Police say are searching for thieves who took at least $40,000 worth of computers from a San Mateo County school.

The Oakland Tribune reports 18 MacBook Pro computers were stolen late Thursday from El Crystal Elementary School in San Bruno.

Principal Skip Johnson tells the newspaper one of the thieves apparently suffered a cut during the break in and left behind a blood sample. The blood could help detectives track down a suspect if that person had prior convictions that led to submission of a DNA sample to authorities.

Johnson tells the Tribune he suspects the thieves had some familiarity with the school's operations because they concentrated on the computers. Nothing else appears to have been taken.

Police haven't said if they have any suspects.

MAN ON FIRE ON NAPA OVERPASS WAS DA'S SON: NAPA . (AP) — Authorities say the man who died after being spotted on fire on a highway overpass in Napa was the son of Napa County District Attorney Gary Lieberstein.

Sheriff's Capt. Tracey Stuart identified the man as Lieberstein's son, 31-year-old Adam.

He was spotted on fire on a pedestrian overpass above Highway 29 on March 26. Authorities had initially considered the possibility the incident was a homicide.

But Stuart says there are strong indications now that it was a suicide.

The district attorney contacted the sheriff's office a few days after the incident fearing that it was his son after not hearing from him since March 25.

Dental records confirmed the identity.

Stuart says the DA and his family were not aware of any problems their son may have had.
