CINCINNATI (WKRC) - The suspect accused of killing a man behind a West End restaurant was arraigned on a murder charge.

A judge ordered Darnell Nelson held on a $1 million bond Friday.

Assistant prosecutor David Wood said in court that Nelson admitted his involvement in the murder of 67-year-old Walter Metz Jr. Thursday afternoon. Metz was killed in an alley behind the Hook Fish and Chicken at about 12:30 p.m.

Witnesses told police they saw someone run from the alley into a house on Dayton Street.

SWAT officers then surrounded the home after the suspect reportedly barricaded themselves inside. They then searched the building for the suspect but were unable to find them.

Officers tracked down Nelson Thursday evening.

Wood also said Nelson was on parole for a federal gun possession charge at the time of the murder and requested the high bond.

Police are looking into whether this homicide is connected to another fatal shooting in the West End 12 hours before. Mario Williams was killed at Poplar and Linn streets.

Nelson is only charged in Metz's murder.
