SAN DIEGO - A man arrested on suspicion of taking part in an assault that killed a Chula Vista resident in the Gaslamp Quarter last month pleaded not guilty Monday.
Mahad A. Ahmed, 23, is being held on $1 million bail and is facing 15 years to life in prison if convicted.
Ahmed was already jailed on an unrelated charge when he was re-arrested last Thursday on suspicion of murder in connection with the death of 25-year-old Michael Beaver, according to police.
About 1 a.m. on June 15, Beaver got into a dispute with a group of men and women for unknown reasons in the 500 block of F Street, said SDPD homicide Lt. Mike Hastings.
After exchanging hostile words with Beaver, three of the others – two men and a woman -- pummeled him in the upper body. They then walked off along with another woman, leaving Beaver unconscious on the sidewalk.
Paramedics took Beaver to a hospital, where he was pronounced dead a short time later.
Surveillance cameras captured images of the assailants. No other arrests have been announced in the case, however. Investigators believe Ahmed, who has a long criminal history including burglary and assault with a deadly weapon, is the one who struck the deadly blow.
Roughly five hours after the confrontation on June 15, Ahmed was booked into jail on an alleged parole violation, according to jail records. Investigators say the victim's blood was on Ahmed's clothing when he was taken into custody.
