The partner of the grandmother of a missing British schoolgirl has been charged with the 12-year-old’s murder.

The charge came as police 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 blamed “human error” and apologized for “the distress and concern” caused by the delay in finding Sharp’s body, which was discovered on Friday in the house – her 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.

Neither suspect was identified by name in line with British practice, and police did not disclose what relationship, if any, the suspects had with the victim.

The discovery of the body led to anger and disbelief in Britain. The family’s frantic search and appeals had even managed to displace much of the feel-good Olympic coverage from the front pages of the nation’s tabloids, with at one point The Sun offering STG25,000, for the tip that led to the girl’s safe return.

The Daily Mirror newspaper asked its readers “WHY DID IT TAKE COPS 8 DAYS?” with the figure 8 outlined in red. The Daily Mail was even more critical, writing under a bold-faced “SHAMBLES” headline.

Police have not specified exactly where in the house the body was found, but Scotland Yard Commander Neil Basu said they had been juggling several different leads with detectives sifting through 60 sightings of the missing girl, 300 calls, and 800 hours of surveillance footage.
