ALBAN AJAEGBO V. THE STATE (2018)

Background

Alban Ajaegbo was the first accused person among seven persons prosecuted before the High Court of Imo State for the murder of Anthony Ikechukwu Okoronkwo, an eleven-year-old boy. The prosecution alleged that the deceased was lured into the premises of the Otokoto Hotel in Owerri, killed, decapitated, and buried in a shallow grave. His severed head was later found in the possession of Innocent Ekeanyanwu, a gardener and hotel worker. Following police investigation, a headless corpse was exhumed from a cassava farm behind the hotel. Ajaegbo, who worked as a cleaner and had shared a room with Ekeanyanwu and another accused person, was subsequently arrested and charged with murder under section 319(1) of the Criminal Code applicable in Imo State.

Ekeanyanwu made statements to the police, admitted killing the deceased, and implicated Ajaegbo and other persons as participants in the killing. These statements were admitted as exhibits 21 and 36. Ekeanyanwu died in prison custody before the trial was concluded and was never tried. The trial court convicted all the accused persons and sentenced them to death. On appeal, the Court of Appeal acquitted some of the accused persons but affirmed the conviction and sentence of Ajaegbo, Sampson Nnamito, and Vincent Duru. Ajaegbo appealed further to the Supreme Court.

Issues

1. Whether the trial court and the Court of Appeal were right to admit and rely on exhibits 21 and 36 in convicting Ajaegbo.
2. Whether the circumstantial evidence against Ajaegbo was cogent, irresistible, and compelling enough to sustain a conviction for murder.

Ratio Decidendi

The Supreme Court allowed the appeal and held that the prosecution bears the unchanging burden of proving every essential element of a criminal offence beyond reasonable doubt. This burden remains on the prosecution throughout the trial and does not shift to the accused. By virtue of section 36(5) of the 1999 Constitution and section 135 of the Evidence Act, an accused person is presumed innocent and has no obligation to establish his innocence.

The Court distinguished between the admissibility of a document and the weight or probative value that may properly be attached to it. Exhibits 21 and 36 were relevant and could be admitted for the limited purpose of proving that Ekeanyanwu made statements to the police and that information supplied by him led to the discovery of the headless corpse. However, the statements could not be treated as proof of the truth of their contents against Ajaegbo. In particular, a confession is ordinarily evidence against its maker alone. Under section 29(4) of the Evidence Act, a confession made by one jointly charged person cannot be considered against a co-accused unless it was made in the co-accused’s presence and adopted by words or conduct. There was no evidence that Ajaegbo heard, adopted, or otherwise accepted Ekeanyanwu’s statements.

The Court further held that section 30 of the Evidence Act, concerning facts discovered as a consequence of information received from an accused person, did not authorise the courts to use the contents of Ekeanyanwu’s statements as substantive proof of Ajaegbo’s guilt. The provision permitted proof of the fact discovered, not proof of every allegation contained in the inadmissible or limited-purpose statement.

Court Findings

There was no eyewitness evidence connecting Ajaegbo with the killing. The independent facts established by the prosecution were that the deceased had been on the hotel premises, Ekeanyanwu had been arrested with his severed head, the body was discovered in a grave behind the hotel, and Ajaegbo had shared accommodation with Ekeanyanwu. Ajaegbo had also made inconsistent statements about whether he saw hotel workers eating the deceased’s groundnuts and whether he knew who owned the farm where the body was found.

The Supreme Court found that these circumstances created suspicion but did not irresistibly establish that Ajaegbo participated in the murder. Circumstantial evidence may be sufficient to ground a conviction, and may sometimes be stronger than direct evidence, but it must exclude every reasonable possibility that another person committed the offence. The inferences drawn by the lower courts—that Ajaegbo must have seen the deceased, must have participated in eating the groundnuts, or must have known what happened because he shared a room with Ekeanyanwu—were speculative. The courts had effectively used exhibit 36 as the standard against which the other evidence was measured, despite the prosecution’s express position that the statement was not tendered to prove the truth of its contents.

The Court also reaffirmed that the mere fact that an accused person lies or gives inconsistent accounts does not itself prove guilt. Nor can grave suspicion replace legal proof. The essential elements of murder required proof that the deceased died, that his death resulted from the act or omission of the accused, and that the act was intentional, with knowledge that death or grievous bodily harm was its probable consequence. Although the death was proved, the prosecution failed to prove beyond reasonable doubt that Ajaegbo caused it or intentionally participated in it.

Conclusion

The Supreme Court held that the prosecution’s case fell below the constitutional and evidential standard required for a murder conviction. The judgment of the Court of Appeal affirming Ajaegbo’s conviction and death sentence was set aside. The conviction and sentence imposed by the trial court were quashed, and Alban Ajaegbo was acquitted and discharged.

Significance

The decision is significant for Nigerian criminal procedure and evidence law. It confirms that a co-accused’s confession cannot be converted into evidence against another accused merely because it implicates that person or leads investigators to relevant physical discoveries. Courts must respect the purpose for which evidence was tendered and must not independently extract incriminating assertions from a document admitted for a restricted purpose. The case also reinforces the strict standard governing circumstantial evidence: association with a suspect, shared accommodation, inconsistent statements, or suspicious conduct may justify investigation, but they cannot sustain a conviction unless they form a complete and compelling chain pointing exclusively to the accused’s guilt.
