(AP) LONDON - The partner of the grandmother of a missing British schoolgirl has been charged with the 12-year-old's murder.

Meanwhile, police have apologized to Tia Sharp's mother after they failed to find the girl's body in her grandmother's house the first three times they searched it.

Scotland Yard is blaming "human error" and has apologized for "the distress and concern" caused by the delay in finding the body, which was discovered Friday in the house — the girl's last known whereabouts — one week after she disappeared in south London.

Stuart Hazell, the 37-year-old partner of Tia's grandmother Christine Sharp, has been charged with murder and will appear in court on Monday.

Two others, a 46-year-old woman arrested on suspicion of murder and a 39-year-old man suspected of "assisting an offender," have been bailed to return to a London police station.
