Hammer-wielding man ‘murders at San Diego McDonald’s’

A hammer-wielding attacker with a ‘cone of red hair’ has been arrested for beating a man to death outside a San Diego McDonald’s. 

Greg Jennings, 50, is accused of launching the shocking attack at a bus stop outside the fast food restaurant on Monday night. 

Passengers on a bus which was preparing to stop there say they witnessed it and cried in disbelief as he beat the unidentified victim relentlessly.

Some witnesses first described Jenning as wearing a Santa Claus hat. 

When police arrested him, they learned they had mistaken his hair for the hat. 

By the time authorities arrived at the scene, the beaten man had lost consciousness. 

They performed CPR but he was declared dead not long after paramedics arrived. 

Jennings was arguing with the man, according to San Diego Police Department, and launched the attack quickly. 

He delivered a string of quick-fire blows to the victim’s face and head before he was arrested, they said. 

It is not known what they were fighting over or if they knew one another. 

Witnesses on a bus watched as it pulled up to this bus stop where they say Jennings (not pictured) was beating the man with a hammer 

He was booked into the San Diego County Jail on Tuesday on a single murder charge. 

Victims told The San Diego Tribune the scene was ‘traumatizing’. 

‘There were people screaming and crying,’ Melanie Miller, who watched from a bus,’ said. 

The unidentified victim died at the scene. The pair were arguing before Jennings attacked him, according to police
