*1044 Opinion
The California Street Terrorism Enforcement and Prevention Act (the STEP Act; Pen. Code, § 186.20 et seq.)
1
criminalizes active participation in a criminal street gang (§ 186.22, subd. (a)). A criminal street gang is any ongoing association that has as one of its primary activities the commission of certain criminal offenses and engages through its members in a “pattern of criminal gang activity.” (§ 186.22, subd. (f); see
People
v.
Loeun
(1997) 17 CalAth 1, 4 [
I.
On May 6, 1997, Due Vuong, a member of OPB (Oriental Play Boys), a criminal street gang, was accosted at a gas station by members of the rival criminal street gang VFL (Vietnamese for Life). The VFL members fled when Vuong fired a warning shot at their car. Later that day, three armed and masked men chased Vuong through his apartment complex, shooting at him and wounding him in the shoulder. A short time later, two masked men fired shots at 18-year-old Lon Bui as he was crossing the street to the apartment complex, killing him. Bui was not a member of any gang.
Qui Ly, a member of V (Vietnamese Boys), a gang affiliated with VFL, testified about the attacks. He stated defendant Quang Minh Tran was a “shot-caller” for VFL. Defendant called Ly a few hours after Vuong fired the warning shot, telling Ly he needed guns to retaliate against OPB for the disrespect Vuong had shown VFL. Ly brought two guns to a meeting with defendant and several other V and VFL members. Defendant armed himself with a TEC-9 automatic weapon, choosing it for himself because it tended to jam after a round was fired and he knew how to clear it. They drove to Vuong’s apartment complex, where Ly, defendant and “Uncle Dave,” another VFL member, donned masks and went to look for Vuong. They found him attempting to retrieve something from the trunk of his car. All three men *1045 began shooting at Vuong, who ran to his apartment, chased by defendant and his companions. Someone inside the apartment opened the door, kicking it closed after Vuong ran inside. One of the men chasing Vuong kicked the door open, fired several shots into the apartment, and ran off. Vuong’s only injury was a bullet graze to his shoulder. Defendant and Ly ran to the front gate of the apartment complex where they saw Bui. Defendant said, “That’s him, that’s him, that’s Play Boy,” apparently believing Bui was a member of OPB. Defendant then crouched, took aim, and shot Bui in the back as Bui attempted to run away. When defendant later learned the man he killed was not an OPB member, he responded, “Fuck it, like oh well.”
Other evidence also linked defendant to the attacks on Vuong and Bui. Hanh Dam, a V member, testified that a few days after Bui’s murder, defendant warned him to be careful if he saw any OPB members, telling Dam about the incident at the gas station, explaining that defendant had learned where Vuong lived, and telling Dam “they” had shot at Vuong and killed Vuong’s friend. The bullet that killed Bui was consistent with a bullet fired from a TEC-9, and was of the same make as several live rounds recovered from the apartment complex that could have been ejected from a TEC-9 if the weapon had jammed or misfired. A witness who heard shooting saw several men run out of the complex and jump into cars. One of the cars, a burgundy four-door Acura with tinted windows and shiny chrome wheels, met the description of the car defendant drove at that time.
Officer Ronnie Echevarria, a police expert on criminal street gangs, was familiar with VFL, V and OPB, and with the members of each gang. Echevarria testified he knew defendant and knew that on May 6, 1997, defendant was an active participant in VFL, a gang that engaged in extortion, prostitution, robberies, and burglaries as its primary activities. Echevarria was also familiar with gang culture. He stated that respect is of paramount importance to gangs, and that gang members will shoot members of a rival gang to enhance the reputation of their own gang, to benefit their gang’s recruitment processes, and to send the message that gang members will react violently to acts of disrespect committed against the gang.
To establish the predicate offenses required to show a pattern of criminal gang activity, Echevarria testified about Noel Jesse Mata, a VFL member who in 1996 shot three men he believed to be members of OPB to retaliate for the 1992 death of another VFL member. Over defendant’s objection, Echevarria also testified about a series of extortions defendant and several other VFL members had undertaken in 1993 and 1994 against Vietnamese businesses. Echevarria stated that VFL members had fired shots into some businesses and had made threats against others. Defendant, defendant’s brother, and another VFL member had been arrested and prosecuted as the result of a “sting” in *1046 which a cooperating business owner paid protection money to defendant. The prosecution also provided the jury with certified copies of court records establishing that Mata had been convicted of offenses arising from the 1996 shootings, and that defendant, on a plea of guilty, had suffered a conviction resulting from a 1994 extortion. 2
Defendant was convicted, following a jury trial, of first degree murder (§ 187, subd. (a)), attempted premeditated murder (§§ 187, subd. (a), 664), and active participation in a criminal street gang (§ 186.22, subd. (a)). The jury also found defendant had personally used a firearm in the commission of a felony or attempted felony (§ 12022.5, subd. (a)) and had committed the murder and the attempted murder for the benefit of, at the direction of, or in association with a criminal street gang (§ 186.22; subd. (b)). The trial court sentenced defendant to a term of 25 years to life for murder and a consecutive term of life for attempted murder, adding a 10-year enhancement to each term for the use of a gun and a three-year enhancement to each term for the gang enhancement. It imposed an additional consecutive term of three years for active participation in a criminal street gang. The Court of Appeal modified the judgment to stay the three-year term imposed for active gang participation and affirmed the judgment as modified.
II.
We have not directly considered whether a defendant’s offense on a separate occasion might qualify as a predicate offense to establish a “pattern of criminal gang activity” under the STEP Act. (§ 186.22, subd. (f).) In
People
v.
Gardeley
(1996)
III.
Defendant contends that even if the STEP Act allows a predicate offense to be established by evidence of a defendant’s offense on a separate occasion, the inherent prejudice in such evidence generally requires its exclusion under Evidence Code section 352, which provides; “The court in its discretion may exclude evidence if its probative value is substantially outweighed by the probability that its admission will . . . create substantial danger of undue prejudice, of confusing the issues, or of misleading the jury.”
*1047
Without doubt, evidence a defendant committed an offense on a separate occasion is inherently prejudicial. (See
People v. Ewoldt
(1994)
In
Ewoldt,
for example, a prosecution for lewd acts committed against a child under the age of 14 years, we concluded that the trial court had not abused its discretion by admitting evidence the defendant had committed other, uncharged lewd acts against the victim and her sister. Although the evidence was prejudicial to the defendant, it was also probative, strongly suggesting a common design or plan. (Evid. Code, § 1101, subd. (b);
People
v.
Ewoldt, supra,
The probative value of the evidence is enhanced if it emanates from a source independent of evidence of the charged offense because the risk that the witness’s account was influenced by knowledge of the charged offense is thereby eliminated.
(People
v.
Ewoldt, supra,
In
Ewoldt,
we concluded that the totality of the circumstances supported the trial court’s decision to admit the evidence of the defendant’s uncharged criminal acts. And we so concluded even though not all of the listed factors weighed in favor of admitting the evidence. Thus, we found the evidence admissible although the source of the testimony relevant to the uncharged acts was not wholly independent of the evidence of the charged offense, and the uncharged acts had not resulted in a criminal conviction.
(People v. Ewoldt, supra,
*1048
In cases such as
Ewoldt,
where evidence is admitted under Evidence Code section 1101, subdivision (b), the evidence is probative because of its tendency to establish an
intermediary fact
from which the ultimate fact of guilt of a charged crime may be inferred.
(People
v.
Ewoldt, supra,
At the same time, the inherent prejudice from a defendant’s separate gang-related offense typically will be less when the evidence is admitted to establish a predicate offense in a prosecution for active participation in a criminal street gang, than when it is admitted to establish an intermediary fact from which guilt may be inferred. “Prejudice for purposes of Evidence Code section 352 means evidence that tends to evoke an emotional bias against the defendant with very little effect on issues, not evidence that is probative of a defendant’s guilt.”
(People
v.
Crew
(2003)
Defendant argues that evidence of a defendant’s separate offense on another occasion should not be admitted when it is “cumulative.” By this he seems to mean that the evidence should not be admitted when the prosecution has the ability to develop evidence of offenses committed on separate occasions by other gang members. But defendant cites no authority for the
*1049
argument that the prosecution must forgo the use of relevant, persuasive evidence to prove an element of a crime because the element might also be established through other evidence. The prejudicial effect of evidence defendant committed a separate offense may, of course, outweigh its probative value if it is merely cumulative regarding an issue not reasonably subject to dispute.
(People
v.
Ewoldt, supra,
7 Cal.4th at pp. 405-406;
People v. Williams
(2009)
That evidence of a defendant’s separate offense may be admissible to prove a predicate offense does not mean trial courts must in all cases admit such evidence when offered by the prosecution. Considerations such as those described in People v. Ewoldt, supra, 7 Cal.4th at pages 404-405, will still inform the trial court’s discretion and in an individual case may require exclusion of the evidence. Further, although the court need not limit the prosecution’s evidence to one or two separate offenses lest the jury find a failure of proof as to at least one of them, the probative value of the evidence inevitably decreases with each additional offense, while its prejudicial effect increases, tilting the balance towards exclusion. And the trial court of course retains discretion to exclude details of offenses or related conduct that might tend to inflame without furthering the purpose for admitting the evidence.
*1050 IV.
Turning to the present case, we find the admission of evidence of defendant’s conviction of extortion and related activities in 1993 and 1994 to have been a proper exercise of the trial court’s discretion under Evidence Code section 352. The evidence was highly probative on several issues relevant to the charge of active participation in a criminal street gang, providing direct evidence of a predicate offense, that defendant actively participated in VFL, and that defendant knew VFL engaged in a pattern of criminal gang activity. Defendant’s conviction of extortion occurred several years before his arrest on the current charges. The probative value of the evidence accordingly was enhanced because the evidence emanated from independent sources that could not have been influenced by knowledge of the charged offenses. (.People v. Ewoldt, supra, 7 Cal.4th at pp. 404-405.) Further, as the prosecution’s evidence of predicate offenses consisted only of evidence of the charged offenses, evidence Noel Jesse Mata shot three men in 1996, and evidence of defendant’s extortion activities and conviction in 1993 to 1994, the evidence of defendant’s extortion activities and conviction was not particularly cumulative and certainly not so cumulative as to lack probative value.
Nor was the evidence unduly prejudicial. As we have explained, that the evidence tended to establish elements of the prosecution’s case did not render it prejudicial for purposes of Evidence Code section 352.
(People v. Doolin, supra,
The probative value of the evidence thus far outweighed its prejudicial ' effect, justifying the trial court’s decision to admit it.

The judgment is affirmed.
