Police are now saying a string of unprovoked stabbings that ended in a high-profile arrest on Alamitos Beach started two days earlier when the suspected assaulted a man and a woman in separate attacks on Oct. 15, two days before he would go on a rampage that ended with one person dead and four others wounded.

In total, police and prosecutors now allege that 21-year-old Yohance Sharp used a knife to attack or threaten eight people: Two on Saturday, Oct. 15, and six on Monday, Oct. 17.

The first attacks were on Anaheim Street near Atlantic Avenue, within a block or two of Sharp’s apartment on Lime Avenue, where his girlfriend said the couple had lived for several months. Sharp, who suffers from schizophrenia, had gone off his medication a few months earlier after a doctor said he could try functioning without it, according to the girlfriend, Yessenia Partido.

Partido said she didn’t know about the attacks Saturday night. She’d been trying to get Sharp to go back on his medication over the weekend, but she left on Sunday when Sharp began talking about killing people.

Police said Sharp’s spree Monday morning involved six victims. He’s accused of killing 62-year-old Tina Hook outside a county-run temporary housing facility at 1133 Atlantic Ave—about a block from his apartment—at around 5:30 a.m.

Over the next hour and a half, he allegedly wounded four more people, including two near the Alamitos Beach bike path where he was taken into custody. Police say he threatened two additional victims who were not wounded.

That afternoon, Partido said, she returned to her apartment with a social worker only to find out later that her boyfriend had been arrested in connection with the wide-ranging violence.

The Los Angeles County District Attorney’s office has charged Sharp with five counts of attempted murder, one count of assault with a deadly weapon, and one count of murder. Sharp is also facing a misdemeanor charge for obstructing an officer, according to a felony complaint filed in Long Beach Superior Court.

Sharp is also accused of violating his probation on two prior convictions: a hit-and-run crash in April 2020 and an assault at a Hawthorne park in July 2020.

Police records reviewed by the Post show the assault charge stemmed from a fight he instigated at the park in Hawthorne. Sharp returned after the fight and chased the victim with a knife, according to police. He pleaded no contest in both cases and was ultimately sentenced to 292 days in jail and two years of probation, court records show.

The motive for Monday’s attacks remains under investigation, but police said the stabbings appear to have been unprovoked and the suspect and victims did not know each other.

On Wednesday, a Long Beach Superior Court judge increased Sharp’s bail to $7.06 million. He didn’t appear in court Wednesday but was expected to on Thursday afternoon.

Partido said she hopes Sharp is getting his medication while in custody.
