BOSTON -- The search for a 5-year-old boy missing for more than a week focused on a cemetery in Lynn on Monday, the Lynn Daily Item said.

Teams Search Cemetery For Missing Boy

Lynn and state police used K-9 cadaver dogs in their search of Pine Grove Cemetery for Giovanni Gonzalez.

Giovanni was reported missing on Aug. 18 when the boy's father, Ernesto Gonzalez, 36, of Lynn, failed to return the boy to his mother, according to police.

Giovanni was brought by his mother to his father's home at 2 Brightwood Terrace in Lynn on Aug. 15 for a weekend visit. Police said Gonzalez did not return Giovanni to Daisy Colon, 22, of East Boston, at the end of the weekend.

Gonzalez was arrested last week and charged with child endangerment. He was ordered held on $500,000 cash bail following his arraignment in Lynn District Court. Officials were concerned because Gonzalez had a cut on his left finger, and he gave conflicting accounts of how the injury happened, the paper reported.

Last week, investigators found a bloody mop in Gonzalez's apartment, according to a search warrant. Boots with red-brown stains, stained jeans and two knives -- one that was found on the kitchen floor -- were also removed from the apartment. Investigators did not say what type of blood was on the confiscated items.

Giovanni weighs approximately 40 pounds and is 49 inches tall with black hair and brown eyes. When last seen, he was wearing blue denim jeans, a red T-shirt, a silver braided chain and black Spider-Man sandals. He was carrying a black backpack that had the Transformers robot characters on it. It contained some of his clothes and toys.

He has a faded skin pigmentation mark on the lower right side of his chest and a small scar above his eyebrow.

Anyone with information about the child's disappearance or whereabouts is asked to call 911 or Lynn police at 781-595-2000.
